Kiana, do you understand what filial piety is?

229 Brother Yuzhe, I'll be waiting for you in the room tonight~

Chen Tianwen stretched out her trembling hand, and her fingertips lightly touched Yu Zhe's zipper, but this simple touch made her shrink as if she had been electrocuted, but she quickly mustered up the courage to move closer again.

When the zipper was slowly opened, Chen Tianwu gasped, her eyes widened, and her thick eyelashes trembled constantly.

"Wow, what a big brush..." Chen Tianwen muttered to himself unconsciously, then realized what he said, and his whole face suddenly turned red as if blood was dripping.

She looked away in panic, but couldn't help but take a sneak peek.

The slender fingers touched it carefully, and Chen Tianwen's palm immediately felt an astonishing heat. She pulled her hand back again as if burned, but soon, slowly and firmly grasped it.

At this moment, her heart was beating so fast that it almost jumped out of her chest, and she could even hear her own violent heartbeat echoing in her ears.

Chen Tianwen's hands were shaking a little, which reminded her of the first time she wrote calligraphy.

But this paintbrush is bigger than a brush and more difficult to control.

"Brother Yuzhe, I'm sorry... I may not be able to use it very well..." Chen Tianwen stuttered, but his hands gradually found the rhythm.

As her thumb gently stroked the tip of the pen, she heard Yu Zhe let out a suppressed groan and looked up in surprise.

Seeing Yu Zhe's forbearing expression, Chen Tianwen felt a strange sense of satisfaction for some reason.

"Brother Yuzhe...is this how I use the pen, right?" she asked, mustering up the courage, her voice filled with a hint of anticipation and shyness, her hands unconsciously moving a little faster.

Yu Zhe's Adam's apple rolled up and down, his eyes half-closed, his voice hoarse: "That's right, keep going... don't stop..."

Chen Tianwen's movements became bolder. She tentatively ran her fingertips across the tip of the pen. Hearing Yu Zhe gasp, she couldn't help but let out a shy yet smug smile.

"So this is how it's supposed to be used..." she muttered softly, deliberately staying there for a while longer.

Yu Zhe suddenly grabbed her wrist, his eyes narrowed dangerously: "Little girl, did you do this on purpose?"

Chen Tianwen was startled by his reaction, but she quickly gathered her courage and blinked her big watery eyes: "I, I just want to paint well with my paintbrush..." As she spoke, she deliberately slowed down her movements.

Yu Zhe's breathing became noticeably heavier. He released her wrist and asked, "Where did you learn these..."

Chen Tianwen's face turned even redder, and his voice was as thin as a mosquito: "I... I have read some... novels..."

"Novel?" Yu Zhe suddenly chuckled and reached out to touch her cheek. "My little Tianwen, when did you become so bad?"

Chen Tianwen was so startled by his sudden action that he almost let go, but he quickly regained his composure and mustered up the courage to look him straight in the eye: "So...does Brother Yuzhe like the bad side of me?"

Yu Zhe's eyes darkened and he didn't answer. He just suddenly held her hand and led her to speed up.

Chen Tianwen exclaimed, feeling the temperature of her palm getting higher and higher, and the touch of the paintbrush made her heart beat like thunder.

"Ah...Brother Yuzhe..." She looked at him bewilderedly, but he suddenly kissed her lips. The kiss was so sudden and passionate that Chen Tianwen felt like she was melting, but her hands continued to move instinctively.

When Yu Zhe finally let go of her lips, both of their breathing became a mess. Chen Tianwen saw the gleam in Yu Zhe's eyes and suddenly felt a wonderful sense of accomplishment.

"Can I...can I continue?" she asked in a low voice, her fingers moving restlessly.

Yu Zhe took a deep breath and reached out to ruffle her hair: "Little rascal... whatever you want."

At this moment, there was a sudden sound of footsteps outside the door.

Yu Zhe and Chen Tianwen were both stunned, but they quickly guessed who would come.

"Brother Yuzhe..."

"Wait, let's finish this. Put on your clothes first."

"Yeah." Chen Tianwen nodded, then put on his clothes as quickly as possible.

Yu Zhe also sprayed air freshener in the laboratory to prevent Chen Tianwu from noticing anything unusual.

Just as Yu Zhe and Chen Tianwen were getting ready, the door of the room was suddenly pushed open, and Chen Tianwu rushed in. Her eyes were full of anxiety and worry, like a hen looking for her children.

"Yu Zhe!" she shouted, her voice echoing in the laboratory.

Yu Zhe stood up and said to Chen Tianwu with a smile: "What's wrong? Is there anything you want to talk to me about?"

"Where is my sister?" Chen Tianwu walked quickly to Yu Zhe, staring at him intently, as if he wanted to see through him.

Without waiting for Yu Zhe to speak, Chen Tianwen spoke, "Sister, I'm here."

Hearing Chen Tianwen's voice, Chen Tianwu immediately turned around and saw Chen Tianwen with a rosy face.

"Tianwen, how are you? Did Yu Zhe do anything to you?!" Chen Tianwu walked quickly to Chen Tianwen and held her shoulders tightly with both hands.

"No, no." Chen Tianwen shook his head frantically, waving his hands as if trying to prove his innocence. "Brother Yuzhe just checked my body."

Chen Tianwen looked at his sister and felt a warm feeling in his heart. Suddenly, he thought of what had just happened and his face couldn't help but blush again.

Chen Tianwu seemed to notice something was wrong with her sister. She frowned, her eyes full of suspicion, and asked, "Tianwen, what's wrong with you? Why is your face so red? Are you feeling unwell?" Her hands gently stroked Chen Tianwen's cheeks, as if checking if she had a fever.

Chen Tianwen shook his head in panic and said, "No... no, I'm fine." But her evasive eyes and red cheeks made Chen Tianwu even more suspicious.

Yu Zhe quickly explained, "Tianwen might have been a little nervous during the examination just now and sweated a lot, so his face is so red."

Chen Tianwu listened with half belief and half doubt.

She still remembered what Yu Zhe did when he examined her.

"Sister, I'm a little tired and want to rest." Chen Tianwen said softly, with a hint of fatigue in his voice.

Chen Tianwu took a deep breath and temporarily suppressed the doubts in her heart, "Okay, let's go back and rest." But the moment she turned around, she glared at Yu Zhe with a warning look, as if telling him that if he dared to bully Chen Tianwen, she would never let him go.

When Chen Tianwu and Chen Tianwen walked out of the laboratory, Chen Tianwen suddenly stopped and gently tugged at his sister's sleeve. "Sister, I think I left something in the lab. Wait for me."

Before Chen Tianwu could react, she ran back to the laboratory like a gust of wind, leaving Chen Tianwu alone there.

In the laboratory, Yu Zhe was tidying up the instruments and was startled when he heard the door being pushed open.

He turned around and saw Chen Tianwen, who was panting, and asked in surprise: "Tianwen, why are you back..."

Before Yu Zhe could finish his words, Chen Tianwen ran up to Yu Zhe, stood on tiptoe and gently pressed her lips against his.

The touch at that moment was like a feather brushing past, carrying the unique sweet fragrance of a young girl.

"Tonight..." Chen Tianwen took a step back, his voice trembling but sweet, "I'll be waiting for you in the room tonight~Brother Yuzhe~"

After saying that, Chen Tianwen ran out of the laboratory with a red face.

230 Chen Tianwu: Sister, please listen to my explanation!

Chen Tianwu looked at Chen Tianwen who suddenly ran back, with a hint of doubt in his eyes, "Tianwen, what on earth did you leave behind?"

Chen Tianwen stopped and lowered her head slightly. Her long hair covered half of her face, making her look particularly shy. "I didn't forget anything, sister. I...I remembered it wrongly."

Upon hearing this, Chen Tianwu frowned slightly and glanced back and forth at Chen Tianwen, trying to find flaws in her expression and movements.

"Really?" Chen Tianwu's voice was still filled with doubt, but she did not continue to ask, perhaps because she trusted her sister, or perhaps she also hoped that it was just her own worry.

Chen Tianwen nodded gently, "Well, I must have remembered it wrongly. Let's go back, sister."

Having said that, she turned around to leave, but at the moment she turned around, she secretly looked back at the door of the laboratory.

Chen Tianwu noticed the change in his sister's eyes and suddenly stopped. His voice was a little lower than usual. "Tianwen, is there something I want to tell you?"

Chen Tianwen was startled when he heard this, and raised his head with confusion in his eyes: "What's the matter? Why is my sister suddenly so serious?"

Chen Tianwu took a deep breath, his hands unconsciously clenching and unclenching: "You are not allowed to be alone with Yu Zhe anymore, understand?"

"Why?" Chen Tianwen's eyes widened instantly, his face filled with disbelief. "Brother Yuzhe is a very good person..."

"There's no reason." Chen Tianwu interrupted her, his tone so firm that even he was surprised.

But just as she finished speaking, Chen Tianwu saw a flash of hurt in Chen Tianwen's eyes. Her heart ached, but she still hardened her heart and continued, "Tianwen, I'm doing this for your own good."

Chen Tianwen bit his lower lip, his eyes moving away from his sister's face and falling on the door of the laboratory at the end of the corridor. His voice was so soft that it was almost inaudible: "But..."

"No buts." Chen Tianwu interrupted Chen Tianwen and forced her to look at him.

Then Chen Tianwu saw the tears in Chen Tianwen's eyes, and his heart softened. But thinking of those suspicious signs, he had to harden his heart: "Be obedient, okay?"

The light in the corridor cast a long, thin strip of light on the ground. Chen Tianwen stared at the light for a long time. Finally, she nodded gently: "I, I understand."

Chen Tianwu breathed a sigh of relief and reached out to ruffle her sister's soft hair. "Tianwen, I know you may not understand me, but you will understand in the future." Her voice softened, with a hint of pleading, "I'm protecting you."

Chen Tianwen raised his head and forced a smile.

"Ah."

As soon as the words fell, the air between the two seemed to freeze for a moment.

“Click…”

The sound of the laboratory door lock turning came from a distance. Chen Tianwen's body visibly stiffened, but she quickly concealed it and took the lead. "Let's go, sister."

Chen Tianwu looked at her sister's thin back and felt uneasy. She hurried to catch up and looked back one last time at the corner - the laboratory door was still closed, but for some reason, she always felt that Yu Zhe was watching them leave through the door.

After returning to the room, Chen Tianwen sat on the edge of the bed, his heart full of confusion and entanglement.

She didn't understand why her sister Chen Tianwu suddenly asked her to stay away from Yu Zhe so firmly. Her sister's serious and unquestionable expression and the words "I'm doing this for your own good" kept replaying in her mind.

But when he thought of Yu Zhe, Chen Tianwen's thoughts were like a wild horse that had broken free from its reins, completely out of control.

Yu Zhe's gentle and deep eyes, his magnetic and slightly hoarse voice, and his intimate and shy interactions with her in the laboratory, all kept flashing in her mind like movie scenes.

Chen Tianwen's cheeks gradually turned red and his eyes became blurred.

Her hand unconsciously reached down, and when it touched her own soft skin, her body trembled slightly, and an indescribable numbness instantly spread throughout her body.

The girl's breathing became rapid and her heartbeat was like a drum, which was particularly clear in the silent room.

"Brother Yu Zhe..." Chen Tianwen murmured softly, with a hint of longing and attachment in his voice. Yu Zhe's appearance kept appearing in his mind, as if he was standing in front of him at this moment, looking at him with those gentle eyes.

Just as Chen Tianwen was immersed in his fantasy, there was suddenly a knock on the door.

Chen Tianwen was startled and quickly withdrew his hand like a frightened deer. He hurriedly tidied up his clothes and tried to make himself look normal.

"Who is it?" Chen Tianwen asked, pretending to be calm, but there was a barely perceptible tremor in his voice.

"It's me." Chen Tianwu's voice came from outside the door.

Chen Tianwen breathed a sigh of relief, but a trace of nervousness welled up in her heart. She didn't know why her sister suddenly came to see her.

Chen Tianwen stood up, walked to the door, opened it, and saw his sister standing outside with a complicated look in her eyes.

"Tianwen, I...I want to talk to you again."

Chen Tianwu walked into the room, sat on the edge of the bed, and stared at Chen Tianwen.

Chen Tianwen sat next to his sister, with his head lowered, not daring to look into his sister's eyes, his heart filled with anxiety.

"Tianwen, I don't know what happened between you and Yu Zhe in the lab." Chen Tianwu's voice was very soft, "But I really don't want you to get hurt. Yu Zhe looks gentle on the surface, but he has a deep mind. I'm worried about you..."

"Sister, Brother Yuzhe is not what you think." Chen Tianwen raised his head and interrupted his sister eagerly, with a hint of stubbornness in his eyes. "He is very good to me and respects me. Today in the lab, he just helped me check my body and didn't do anything excessive."

Chen Tianwu looked at Chen Tianwen's eyes full of trust, and her heart ached, but as an older sister, she couldn't bear to watch her sister fall into possible danger.

"Tianwen, you're still young. There are many things you don't understand." Chen Tianwu took a deep breath and tried to calm his tone. "Besides, matters of the heart are very complicated. They're not as simple as you think."

"Why did you say that?" Chen Tianwen's voice trembled slightly. "Could it be that you've fallen in love with Brother Yu Zhe, so you don't want me to like him too?"

Chen Tianwu was shocked by her sister's sudden questioning. She saw tears of grievance welling up in Tianwen's almond-shaped eyes, which were exactly the same as hers.

But Chen Tianwu didn't know how to answer for a moment.

Tianwu's voice was so soft that it was almost inaudible. "Tianwen, that's not what I meant..."

"What does that mean, sister?!"

"I..." Chen Tianwu hesitated for a long time but couldn't say a complete sentence.

231 Chen Tianwen: It hurts! It hurts so much!

Chen Tianwen looked at Chen Tianwu, who seemed to be hesitant to speak and had a complicated expression, and felt even more aggrieved. Tears welled up in his eyes and could burst out at any time.

"Sister, you've been acting so strange today. Ever since you told me not to be alone with Brother Yuzhe, you've been acting strange. What are you hiding from me?"

Chen Tianwen always felt that something must have happened between his sister and brother Yu Zhe.

The scene of Chen Tianwu and Yu Zhe interacting when he picked her up yesterday kept appearing in her mind. Those interactions that seemed normal on weekdays now became suspicious in her eyes.

Could it be that her sister really fell in love with Brother Yu Zhe and that was why she didn't allow her to be with him? Once this thought came to her mind, it grew like a weed in her heart.

But wasn’t my sister a boy before? Can boys like boys too?

If that's the case, what should Sister Anna do?

But if this was really the case, Chen Tianwen felt that Chen Tianwu was being too unfair to Anna, and at the same time, he was filled with resentment towards Chen Tianwu.
