The engagement was with the younger brother, but I've fallen for the older brother.

Si Yimian bit her lower lip, not wanting to go into details.

"It felt like being pricked with needles by Rong Momo, burning, swollen and painful."

He Sichen's expression looked like he had been punched.

We really couldn't stop it last night.

She cried out in pain halfway through because of the excessive frequency and duration of the encounters. He comforted her briefly and then continued.

Now that I think about it, what's the difference between me and an animal?

"When did it start?"

"It was there when I woke up this morning. I thought it would be fine after a good night's sleep, but it just kept getting worse..."

Before she could finish speaking, she looked up at him, her eyes glistening with tears.

He Sichen paused for a moment, put down his cup, and his expression became serious.

"Go to the hospital after you finish eating."

"oh."

She obediently lowered her head and chewed the wontons in small bites.

He put down his coffee cup, stood up, and pushed his chair back.

"Eat slowly, there's no rush."

Si Yimian put a mouthful of wonton in her mouth and nodded blankly.

"Ugh... Ugh!"

……

Yu'an Hospital, VIP Clinic of the Laboratory Department.

The doctor pushed the report over and pointed to the row of data marked in red with his index finger.

"Ms. Si, you have contact dermatitis, which is caused by material intolerance."

"To put it simply, it means I'm allergic to most condom materials on the market."

Dr. Xu looked at Si Yimian, her tone gentle.

"Ms. Si, have you used condoms before?"

Si Yimian shook her head, her ears turning red.

No, this is the first time.

He Sichen sat to the side and heard these three words. His face remained calm, but his eardrums were pounding.

Dr. Xu nodded knowingly and continued.

"Ms. Si, your constitution is rather unique. This type of allergy is rare in clinical practice, but it does happen."

Symptoms include localized burning pain, redness and swelling, mucosal damage, and in severe cases, rashes may appear.

"The symptoms are not severe, but medication is needed. Avoid contact with the allergen again for a week."

Dr. Xu looked past her and at He Sichen.

"Dr. He, since this is your brother's arranged marriage partner, could you please convey that the traditional approach is no longer viable?"

"Young people have a lot of energy, but they also need to be careful not to damage their mucous membranes."

"As the older brother, you should give him more guidance. Don't just be busy; you also need to care about your younger brother's quality of life."

He Sichen took a deep breath.

At thirty years old, this is the first time I've been taught to care about my younger brother's sex life.

Si Yimian's shoulders trembled as she tried to suppress her laughter, and she reached out to tug at his sleeve.

"Dr. He, the doctor is talking to you."

"Your brother... is such a worry."

He Sichen grabbed her wrist with his other hand.

Under the tablecloth, he pressed his thumb hard against the inside of her wrist bone as a warning.

Si Yimian winced in pain, but didn't pull her hand away. Instead, she scratched his palm with her fingertips.

That tiny bit of force felt like a tickle, tickling from the palm all the way down the spine, and then down to the lower abdomen.

He Sichen's Adam's apple bobbed, and he loosened his grip on her wrist.

The doctor is typing on the keyboard, writing a medical record, and muttering to himself.

"Miss Si's constitution is not suitable for handling industrial materials."

"Therefore, we suggest switching to contraceptive methods made of other materials."

"Medications and IUDs are too much trouble. Let Nanxian get a tubal ligation; it's minimally invasive now, and recovery is quick."

"In short, stop using condoms. Every time you use one, she suffers."

He Sichen's face was expressionless, but his ears were already bright red.

The redness spread from the earlobe to the ear tip, and from the ear to the neck.

For the first time in my life, I wanted to find a crack in the ground to crawl into.

"Understood, I will pass it on."

His voice was squeezed out from deep in his throat, hoarse beyond belief.

Dr. Xu prescribed the medicine and handed over the prescription.

"For external use only, apply twice a day for three consecutive days."

"Remember to avoid sexual intercourse in the near future until the inflammation subsides."

She paused, then added.

"Let's talk about it when I'm fully recovered."

Si Yimian nodded obediently: "Okay, thank you, Dr. Xu."

Dr. Xu smiled and added another sentence.

"Ms. Si, please don't be shy."

"Just tell Young Master He to be more careful next time."

Si Yimian almost lost her composure.

She took a deep breath, suppressing her laughter.

"OK."

Looking at He Sichen's lifeless face, she suddenly felt that the trip to the hospital was worthwhile.

It was even better than last night.

Last night was just a physical pleasure.

I feel great today.

Double.

He Sichen glanced over and saw her gloating expression.

My temples throbbed twice.

"Walk."

He turned and walked out.

Si Yimian took the prescription and followed.

He Sichen strode out of the consultation room.

Si Yimian laughed so hard her shoulders shook, and she covered her mouth as she followed behind.

"Dr. He, please slow down..."

She bit her lip to suppress her laughter, jogged after him, and finally couldn't hold back at the corner of the corridor.

"puff……"

Laughter leaked out from between his teeth, like a soda bottle that had been unscrewed, impossible to suppress.

He Sichen's back stiffened, and he quickened his pace.

"Dr. He, your ears are so red."

"The color changes from red on the earlobe to the tip of the ear, like a gradient from a strawberry."

He Sichen didn't turn around, his voice cold and hard: "Shut up."

"Dr. Xu asked you to tell Brother Nanxian to be careful. How do you plan to relay that message?"

She mimicked Dr. Xu's tone, speaking in a serious manner.

He Sichen walked ahead, his temples throbbing, and the veins were bulging.

He paused in his steps.

Si Yimian couldn't brake in time, and her nose hit his back hard.

"hiss……"

She covered her nose, her eyes instantly reddening, and tears welled up in her eyes.

"Dr. He! Could you at least turn on your light when you brake?"

He Sichen turned around and looked down at her.

She tilted her head back, her nose red and her eyes wet.

Poor thing, but serves him right.

"He brought it on himself."

His voice was cold, but he raised his hand and pressed his fingertips against the bridge of her nose, gently rubbing it.

"Did it hurt?"

"no."

Si Yimian's nose tingled from his rubbing, and she continued to press him with a muffled voice.

"You haven't answered my question yet."

He Sichen stared at her for two seconds, then suddenly leaned down and whispered in her ear.

"What does what happened last night have to do with him?"

His magnetic voice was extremely low, his breath brushing against her ear.

Si Yimian's ears went numb, and she shrank her neck.

"It's alright..."

"Then why should we tell him?"

He straightened up, his expression unchanged, and began to change the subject.

"Take it to the pharmacy yourself, it's for external use, apply it as prescribed by the doctor."

He turned and walked forward.

Si Yimian jogged to catch up, and after taking a couple of steps, she spoke again.

"Dr. Crane."

"What is it now, young lady?"

"So what about next time?"

"What next time?"

"It's... the next time, that time."

Her voice trailed off as she twisted the hem of her skirt with her fingers.

"The traditional approach won't work, Dr. Xu said."

He Sichen looked down at her, his eyes as deep as ink.

"You want a next time?"

Was she sent by God to test his humanity, or to send him to his death?

Si Yimian looked up at him, her eyes wide open, as if she had heard something unbelievable.

"You don't want to?"

She paused, her gaze sliding from his Adam's apple to his belt buckle before returning to his original position.

"That's not what you said last night."

He Sichen's brow twitched: "What did I say?"

Si Yimian cleared her throat and lowered her voice to imitate him.

"One more time."

"One more time."

"A billion more times."

He Sichen: "..."
