Solving the case: Combining the police dog's olfactory genes at the beginning

"I'm tired, I'm going to take a nap. Wake me up when it's time to eat."

Once Chen Hao's footsteps disappeared at the end of the stairs, Chen's mother let out a long sigh of relief and slumped onto the sofa.

"How long do you plan to keep this a secret?"

Chen Xuanran's voice trembled.

"Luo Fei and I are serious!"

Mr. Chen took off his glasses and wiped them.

"Xuanran, did you know that your sister wrote love letters to Luo Fei back in high school?"

Chen Xuanran was stunned.

"what?"

"She had a crush on Luo Fei for a whole year."

Mrs. Chen sighed.

"Later, she mustered up the courage to confess her feelings, but was rejected in public. She cried for a whole month after that."

Chen Xuanran was struck dumb.

She suddenly understood why her sister reacted so strongly every time Luo Fei was mentioned.

So you want me to break up with you?

Her voice choked with emotion.

"Is that why?"

"I'm not asking you to break up with me."

Mr. Chen rubbed his temples.

"We hope you'll think carefully about how to handle this. Your sister's mental state has been unstable for years."

Chen Xuanran suddenly stood up.

"What about me? Aren't my feelings important?"

Footsteps suddenly came from upstairs, and the three of them immediately fell silent.

Chen Hao stood at the top of the stairs, frowning as she looked at them.

"What's the noise about?"

"nothing!"

Chen's mother forced a smile.

"Xuanran should go to work now, right?"

Chen Xuanran grabbed her coat and rushed out the door, tears welling up in her eyes.

The moment Chen Xuanran rang the doorbell after get off work, Luo Fei felt his heart pounding so hard it felt like it was going to burst out of his chest.

He subconsciously straightened his shirt collar, and the gift bag he was carrying in his left hand made a slight clinking sound.

"nervous?"

Chen Xuanran turned his head to look at him, a mischievous smile in his eyes.

Luo Fei's Adam's apple bobbed.

"How can you not be nervous when meeting your parents for the first time?"

The door opened.

Mrs. Chen stood at the door with a beaming smile, her gaze quickly sweeping over Luo Fei, her smile lines deepening.

"Oh my, this must be Little Luo! Come in, come in!"

"Hello Auntie."

Luo Fei bowed slightly and handed over the gift bag with both hands.

"It's just a small token of my appreciation, not a token of my respect."

When Chen's mother took the bag, she glanced inside and immediately exclaimed in surprise.

"Hey, this Moutai isn't cheap! Old Chen, come take a look!"

In the living room, Mr. Chen put down his newspaper and stood up. His gaze lingered on Luo Fei for a moment, and a satisfied smile appeared on his face.

"You've gone to so much trouble, bringing such an expensive gift for a simple meal."

"It should."

Luo Fei's palms were slightly sweaty.

"I didn't know what my uncle liked to drink, so I just bought some random things."

Just then, the kitchen curtain was lifted, and a fragrant aroma of food wafted out.

Chen Hao carried out the braised fish, and the moment her eyes met Luo Fei's, she froze on the spot.

"Luo Fei?"

Her voice trembled, the porcelain plate tilted in her hands, and the soup almost spilled.

Mr. Chen caught the plate with lightning speed, but it was too late. The air seemed to freeze.

Luo Fei felt a tightness in his throat. He hadn't expected that the "sister" Chen Xuanran mentioned was actually Chen Hao, whom he had rejected in high school.

"Sis, this is Luo Fei, my boyfriend."

Chen Xuanran stepped forward, his voice tinged with trepidation.

We've been together for three months.

Chen Hao's face turned from red to white, and then from white to green.

Her gaze swept across her family members' faces, finally settling on Luo Fei.

"So...you all knew? You just kept it from me?"

"That's not how it is, sister."

Chen Xuanran wanted to explain.

Chen Hao had already started untying her apron, her fingers turning white from the effort.

"I really am the most superfluous person in this family."

She turned and called out to the kitchen.

"Zhang Yong! Let's go!"

The sound of dishes clattering came from the kitchen, and a tall, thin man wearing glasses rushed out in a panic.

"what happened?"

"go!"

Chen Hao grabbed her husband's wrist and dragged him toward the door.

"stop!"

Chen Xuanran grabbed Chen Hao's wrist.

"Sis, you have to explain yourself clearly today. Why do you hate Brother Luo Fei so much?"

The air in the living room froze instantly.

The remote control in Chen's father's hand fell to the ground with a "clatter," and Chen's mother, who was pouring tea, trembled and spilled hot water all over the table.

Zhang Yong stood at the door, rubbing his hands awkwardly.

Chen Hao shook off her sister's hand and sneered.

"Do I need a reason to hate someone?"

"But Brother Luo Fei clearly..."

"enough!"

Mr. Chen suddenly slammed his fist on the table and stood up, his face ashen.

"What kind of behavior do you two sisters exhibit in front of the guests!"

Luo Fei stood beside the sofa, his gaze shifting between Chen Hao's stubborn profile and the puddle of water on the floor.

he.

"Uncle Chen, can I speak with Chen Hao alone?"

"no!"

Zhang Yong blurted it out, then realized his mistake and awkwardly added something else.

We made plans to go to the movies.

Chen Hao suddenly turned around, her high heels making a crisp sound on the floor.

"Okay, let's talk then."

She walked towards her room without looking back.

"Five minutes, not a second more."

Luo Fei nodded to everyone and followed Chen Hao into the boudoir he had never stepped into before.

The moment the door closed, he smelled a faint lavender scent, exactly the same as the scent that Chen Hao used to carry in her schoolbag back in high school.

The room has been preserved in its stunning original condition.

On the desk was a countdown calendar for the college entrance examination, and on the headboard were yellowed English word sticky notes. Even the bed sheets were the old ones with cartoon patterns.

Luo Fei's fingertips lightly brushed against the row of "Five-Year College Entrance Examination and Three-Year Simulation" books on the bookshelf, and his Adam's apple bobbed.

"Say something quickly."

Chen Hao leaned against the wardrobe with her arms crossed, deliberately avoiding his gaze.

Luo Fei took out a brown paper envelope from the inside pocket of his suit jacket; the edges were already frayed.

Do you remember this?

Chen Hao's pupils suddenly contracted.

That was the letter paper she used in her senior year of high school, with tiny cherry blossoms printed on a light blue background.

"You still keep it?"

Her voice suddenly trembled.

"Not just this one."

Luo Fei carefully unfolded the letter.

"I have treasured all the letters that girls have written to me."

Seeing Chen Hao's instantly gloomy expression, he hurriedly explained.

"Because it is an honor to be liked, I cherish every kind gesture."

Chen Hao snatched the letter and quickly scanned the childish handwriting.

When she turned to the last page, she suddenly froze.

"This is impossible."

Her fingernails almost pierced the paper.

"I never wrote this!"

Luo Fei leaned closer to take a look.

Where it should have ended, there was an extra stroke of unfamiliar handwriting.

"Please be sure to reject me publicly after school, so I can give up and focus all my energy on preparing for the college entrance exam." - Chen Hao

"When Xiaomei handed it to me, this passage was at the very end."

Luo Fei's voice was very soft.

“I thought it was your own request.” Chen Hao’s chest heaved violently. She suddenly lunged at the desk and pulled out a locked diary from deep inside the drawer.

The sound of the key turning was particularly jarring. When she turned to a certain page, she felt as if she had been struck by lightning.

"look at this."

She pointed tremblingly to the words in the diary.

"This is the ending I wrote! 'No matter the outcome, please give me an answer. Don't let me spend my last years of senior year guessing.'"

Luo Fei then pulled out another pink piece of paper from the envelope.

"I found this while tidying up old things last week."

Chen Hao took the paper and recognized her best friend Xiao Mei's exaggerated cursive handwriting at a glance.

It was a blatant love confession, dated the day after she sent the letter.

"So that day."

Chen Hao's voice was fragmented.

"When you publicly said, 'Chen Hao, we're not a good match.'"

"I thought I was helping you."

Luo Fei shook his head with a wry smile.

"If we knew that Xiaomei had tampered with the letter..."

Chen Hao suddenly slammed her fist on the wardrobe.

A rag doll rolled down from the top floor and landed right at Luo Fei's feet. It was a small figure sewn from white cloth, with "Luo Fei" written in red on its chest, and its whole body was covered with fine needles.

The two of them froze at the same time.

"Uh"

Luo Fei bent down to pick up the voodoo doll and casually twirled it around.

So that's why I always have unexplained back pain?

Chen Hao blushed and tried to snatch it.

"give me back!"

Luo Fei dodged while holding the doll high.

"Wait a minute, isn't the placement of this needle a bit too precise?"

He pointed to the silver needles in the crotch area of ​​the little man's pants and exaggeratedly gasped.

"you!"

Chen Hao was both ashamed and anxious, tears welling up in her eyes.

"It was an accident while sewing."

She burst out laughing before she could finish speaking.

Luo Fei took the opportunity to return the doll to her, only to see her suddenly and earnestly pull out all the needles one by one.

Will it really hurt?

She asked softly, tears still clinging to her eyelashes.

Luo Fei paused for a moment, then burst into laughter.

"I was just kidding. But..."

He pointed to his right shoulder.

“There is indeed a birthmark here, exactly the same spot where you just had the needle removed.”

Chen Hao looked up abruptly, and only after seeing his mischievous smile did she realize that she had been tricked again.

She raised her fist to strike, but in mid-air, it turned into an embrace.

"hug."

She spoke with a sob in her voice, like a child who had been lost for many years and finally found her way home.

The moment Luo Fei opened his arms, the door was slammed open.

Zhang Yong stood at the door with a livid face, behind him were the Chen family members who were dumbfounded.

"What are you doing?!"

Zhang Yong's roar made the windowpane vibrate.

Luo Fei's hand was still hanging in mid-air.

"Uh, a friendly hug between classmates?"

Chen Hao wiped away her tears and suddenly bowed deeply to her whole family.

"I'm sorry, I misunderstood Luo Fei for ten years."

She held up the two letters.

"Back then, Xiaomei altered the love letter and then wrote her own letter to sow discord."

Chen's mother was the first to rush in and hug her daughter. Chen's father picked up the letter from the ground, looked at it again and again, and finally patted Luo Fei's shoulder heavily.

Only Zhang Yong remained standing at the door, his face turning from pale to red, looking like a broken traffic light.

For the first time ever, Chen Hao put a piece of braised pork on Luo Fei's plate at dinner.

"Try it, I deliberately put in less sugar."

Luo Fei accepted the chopsticks with a flattered expression, but the tip of the chopsticks accidentally touched Chen Hao's. The two of them pulled their hands back at the same time and burst out laughing.

As the elevator slowly descended, Chen Xuanran stood beside Luo Fei and couldn't help but turn her head to look at him.

"How exactly did you manage to convince my sister? She's not usually so easy to talk to."

Luo Fei smirked and suddenly leaned closer to her.

"Want to know? Give me a kiss and I'll tell you."

"you!"

Chen Xuanran's eyes widened, and her cheeks instantly flushed red.

"This is inside an elevator!"

"Nobody saw it."

Luo Fei pointed to the surveillance camera in the corner of the elevator.

"Besides, it can't be filmed from that angle."

Chen Xuanran bit her lower lip, hesitated for a few seconds, and finally tiptoed to peck Luo Fei's cheek quickly before retreating like a startled little rabbit.

"that's it?"

Luo Fei raised an eyebrow in displeasure.

"This is such a perfunctory job! Give me another one."

"Luo Fei!"

Chen Xuanran stomped his foot in anger.

"Don't push yourself too far!"

Seeing that she was really angry, Luo Fei quickly raised his hands in surrender.

"Okay, okay, I say."

He lowered his voice.

"It's actually very simple. I'll tell you that someone tampered with the love letter my sister wrote back then."

"what?"

Chen Xuanran's eyes widened.

"Who did it?"

"Xiao Mei."

Luo Fei sighed.

"Back then, she liked your sister, so she changed the contents of the love letter to make your sister think I was a frivolous person."

Chen Xuanran frowned.

"This can't be right, right? Xiaomei is still my sister's best friend."

That's why I haven't said it yet.

Luo Fei shrugged.

Believe it or not, this is the truth.

The elevator dinged as it arrived on the first floor, and the doors slowly opened.

Chen Xuanran was still processing the information and followed Luo Fei out of the elevator with some skepticism.

"I'm going to the supermarket to buy a pack of cigarettes."

Luo Fei pointed to the convenience store at the entrance of the residential area.

"Why don't you go to the park and wait for me?"

Chen Xuanran shook his head.

"I'll go with you."

She suddenly thought of something.

"By the way, you never smoke in the office, right?"

Luo Fei naturally took her hand.

"Yes, I don't want you to inhale secondhand smoke."

This small act of thoughtfulness warmed Chen Xuanran's heart, and she unconsciously tightened her grip on his hand.

In the supermarket, Luo Fei skillfully grabbed a pack of his usual cigarettes, and while paying, he also bought Chen Xuanran a bottle of her favorite lemonade.

"Let's go, the park is just across the street."

Luo Fei opened the cigarette pack, took out a cigarette and put it in his mouth, but didn't light it.

The two walked to the zebra crossing and waited for the red light. Chen Xuanran was still thinking about what Luo Fei had just said.

"If Xiaomei really did it, my sister will be very sad if she finds out."

Just then, a sharp child's voice rang out.

"Grandma! I want a balloon!"

Chen Xuanran turned his head and saw a little boy of about three years old break free from his grandmother's hand and happily run towards the balloon vendor across the street.

At the same moment, a van was speeding towards them, the driver seemingly unaware of the red light ahead.

"careful!"

Luo Fei shouted almost reflexively.

Before Chen Xuanran could react, he felt a figure flash beside him.

Luo Fei dashed out like an arrow, and just as the truck was about to hit the child, he pushed the child back to the side of the road, but he couldn't stop himself due to inertia.

"Luo Fei!"

Chen Xuanran's scream pierced the air.

"boom"

With a loud crash, Luo Fei's body was hit head-on by the truck, thrown into the air like a rag doll, and then crashed heavily onto the road a few meters away.

Time seemed to freeze at this moment.

Chen Xuanran's legs went weak. Everything before his eyes turned into slow motion: Luo Fei collapsing, the truck's screeching brakes, the gasps of the surrounding crowd, and the sight of the rescued, unharmed child being quickly carried away by his grandmother. (End of Chapter)
