4 PM.
Lin Chen lay on the old sofa, his body aching with exhaustion. The system window was still open before him, displaying his new stats.

"150 points... not bad," he thought, staring at the numbers. "But I'm still extremely weak compared to others in this world."
The original Lin Chen's memories revealed something—this world... was different. There were powerful people—warriors, cultivators, Awakened—individuals who had surpassed normal human limits.
But that was far from his current reality. For now, he was just a poor high school student in an ordinary neighborhood.
[Hint: Focus on daily missions first. Building a strong foundation with your sister will unlock better missions!]
"Understood."
He heard the sound of small footsteps running in the hallway outside. His heart quickened.
"She's back!"
---
The door burst open.
"Brother! I'm home!"
Lin Mi entered with a broad smile, her old school bag on her back. But when she saw him on the sofa, she suddenly stopped.
"Brother? Why do you look tired? Are you okay?" She ran to him, clear concern in her large eyes.
"I'm fine, just exercised a bit," he said gently. "How was your day at school?"
"It was great! I got full marks in math!" She looked around cautiously. "Brother... did something happen? The door was slightly open, and I saw..."
She saw traces of blood on the floor near the entrance.
"Nothing important. Just some annoying pests came by, but I chased them away." He patted her head. "Don't worry."
Her eyes widened. "Pests? You mean... Zhang Wei and his gang?!"
"Yes. But they won't be coming back."
She fell silent for a moment, then suddenly hugged him tightly. "Brother... brother became strong!"
Her voice trembled, but these weren't tears of sadness. They were tears of joy.
"You've changed, haven't you? Since you woke up, you're completely different!"
He smiled. "Smart kid."
"Yes. I've changed. And from now on, I won't let anyone hurt you."
She raised her head, her eyes gleaming strangely. "Really? Brother will always protect me?"
"Always."
Her smile widened. But there was something in that smile... something deeper. More intense.
"Then... brother is mine alone now!"
[Alert! Change in Lin Mi's emotions detected!]
[Warning: Attachment Level = 78% and rising!]
[Personality Type: Medium-risk Yandere]
"Wait... what?!"
---
"Mi, I have something for you."
He got up from the sofa and took her to her small room. He pulled out the bag and clothes from under the bed.
"Here you go. A gift."
Her eyes widened. She stared at the beautiful pink bag, the new clothes, the simple dress.
"Brother... this... this is for me?"
"Yes. Your old bag was too torn. And the clothes... I thought you'd like them."
She stood silently, staring at the gifts. Then suddenly...
"Broooother!" She threw herself at him, crying hysterically. "I love you! I love you so much!"
He hugged her. "I love you too, Mi."
But her embrace... was strong. Too strong for a ten-year-old girl.

"Wait, what?!"
---
Lin Chen cooked a simple dinner fried chicken with vegetables and rice. He used some money from the system wallet to buy better ingredients.
They sat together at the small table. Lin Mi was wearing her new dress, her face flushed with happiness.
"How does it taste?" he asked.
"Delicious! Brother cooks amazingly!" She ate hungrily, but her eyes never left him.
"Mi, did anything happen at school today?"
She stopped eating. She looked at her plate. "Well... there was a new girl in my class."
"A new girl?"
"Yes. Her name is Xiao Yun. She's very beautiful and rich. All the kids wanted to be friends with her."
"What about you?"
She looked at him. "I tried to be nice to her. But she... she mocked my old bag."
He clenched his fist under the table. "What did she say?"
"She said my bag looked like an old rag. And everyone laughed." Her voice was quiet, but there was buried pain.
"Mi..."
"But now I have a new bag! I'll show them tomorrow!" She suddenly smiled, but her smile was... different. "I'll show her that my brother is better than anyone in the world!"
[Alert: Attachment Level = 85%!]
---
After Lin Mi fell asleep, Lin Chen sat in his room, staring at the system screen.
"System, tell me the truth. My sister... what's happening to her?"
[Answer: Lin Mi has always been attached to you, but your sudden change activated her protective and possessive instincts. Essentially, you are the only person in her life, and now that you've become stronger—it makes her feel safe and happy.]
[But this also means she will become... sensitive to any threat to your relationship.]
"A threat? Like what?"
[Like: other girls getting close to you, new friends, anyone who takes your attention away from her.]
He swallowed. "Is this... dangerous?"
[Currently, no. But you must balance caring for her with having a social life. Yandere personalities can be beneficial—loyal, protective, supportive—but if they feel ignored or jealous, they may become... extreme.]
[Advice: Show her constant love, but set healthy boundaries.]
"Okay... I'll try."
---
The next morning, Lin Chen woke up early. He cooked breakfast, woke Lin Mi, and helped her get ready.
"Brother, will you go to school today?" she asked while eating.
"Yes. I've been absent for three days. I need to go back."
"Then we'll go together!" Her eyes lit up.
Her elementary school was on the same route as his high school, so they usually walked together.
They left the house. Lin Mi was proudly carrying her new bag, wearing her new school uniform.
"Brother, do I look pretty?" she suddenly asked.
"Of course. The prettiest girl in school."
She smiled shyly. "Really? Prettier than all the other girls?"
"Yes, prettier than all of them."
[Affection Points +10]
[Attachment Level: 90%]

They reached the fork where the paths split left for the elementary school, right for the high school.
"Well, Mi, I'll see you after school. Enjoy your day."
She held his hand. "Brother... will you be okay? What if Zhang Wei...."
"Don't worry. He won't dare come near me again."
"Okay..." She slowly let go, but her eyes were still worried. "Brother, if... if any girl tries to get close to you, what will you do?"
Strange question. "Why do you ask?"
"Just... just curious."
"This isn't just curiosity...'
"Well, I'll be polite, but I won't get close to anyone. You're the most important person to me, understood?"
Her smile widened hugely. "Understood! I love you, brother!"
She ran toward her school, but turned back several times to wave at him.
[Warning: Your answer pleased Lin Mi, but it also reinforced her possessive feelings. In the future, be cautious in your interactions with females!]
He sighed. "This is going to be complicated..."
---
Lin Chen entered the school gates. It was a medium-sized high school, the buildings old but clean.
Students were everywhere—chatting, laughing, running. But when they saw him, some stopped.
"Look, Lin Chen's back!"
"My god, I heard he was in the hospital!"
"Didn't Zhang Wei beat him up? How did he recover so quickly?"
Whispers. Stares. Some were sympathetic, others were contemptuous.
He ignored them and headed to his class—Second Year, Class 3.
---
When he entered, everyone fell silent. Thirty students, all staring at him.
"Lin Chen? Is it really you back?" a girl's voice from the back.
He looked. Wang Xiao, a kind classmate who had been one of the few who never bullied him.
"Yes, I'm fine now."
He sat at his desk in the back corner. The seat next to him was empty—no one wanted to sit beside "the weak rat."
He opened his book, pretending to read. But his mind was elsewhere.
[New Mission Available!]
Title: First Day at School - Don't Let Anyone Provoke You
Details: First day after the change. Show everyone you're not the same person. But don't start trouble!
Reward: 30 upgrade points + "Mental Fortitude" skill (Level 1)
"Understood."
---
The teacher entered. Mr Zhang, a man in his fifties with thick glasses.
"Good morning, students. Today we'll review... Lin Chen?!"
He stopped when he saw him. "You... you're back? I thought you were still in the hospital!"
"I'm fine, sir."
Mr. Zhang looked at him with concern. "If you're not feeling well, you can go home—"
"No, I'm truly fine."
Mr. Zhang hesitated, then nodded. "Okay. If you need anything, tell me."
Class began. It was math—a subject the original Lin Chen had been weak in. But Kyle in his previous life had been good at math.
"Lin Chen, can you solve this equation?" Mr. Zhang suddenly asked, pointing to a difficult problem on the board.
Everyone snickered quietly. Lin Chen had never solved a problem correctly before.
But he calmly stood up, walked to the board, and began writing.
One step. Two steps. Three.
The solution was perfect.
Silence.
"This... this is correct," Mr. Zhang said, stunned. "Lin Chen, when did you become good at math?"
"Recently." He smiled and returned to his seat.
The whispers started again, but this time they were different.
"Is this really Lin Chen?"
"Maybe he studied a lot while he was at home?"
"No... there's something different about him."
[Bonus Mission Completed: Impress Your Classmates]

During break, Lin Chen went to the courtyard for some fresh air.
"Lin Chen!"
A sharp voice. He turned to see three girls approaching. The leader was a tall girl with dyed blond hair—Liu Na, Zhang Wei's friend.
"I heard you beat up Zhang Wei." She said coldly. "Did you think you'd suddenly become strong?"
"Not suddenly. I just ran out of patience."
"Really?" She approached him. "Zhang Wei is my friend. And I don't like it when he gets hurt. If you don't apologize to him, I'll make your life hell."
He looked calmly into her eyes. "And what if I don't apologize?"
"Then I'll target your little sister."
His heart stopped.
[Warning! Direct threat to your sister!]
[Emergency Mission: Protect Your Family's Reputation!]
"What did you say?" His voice was low, dangerous.
"You heard me. Lin Mi, right? A cute little girl. It would be a shame if—"
Before she could finish, he grabbed her wrist. Not hard enough to hurt her, but his grip was like iron.
"Listen carefully." He looked into her eyes. "If you come near my sister, or even think about harming her, I'll make sure you and Zhang Wei and your whole gang regret the day you were born. Understood?"
His eyes... they were cold. Almost murderous.
Liu Na trembled. For a moment, she saw something terrifying in him.
"L-let go!"
He released her. She fell to the ground, clutching her wrist.
"Remember what I said." He turned and left.

After school ended, Lin Chen went to pick up his sister from her school.
She was waiting for him at the gate, her new bag on her back, a big smile on her face.
"Brother!" She ran to him and jumped into his arms.
"How was your day?"
"Amazing! All the girls loved my bag! And Xiao Yun—the girl who mocked me—went completely silent!" She laughed happily.
"That's good."
They walked home together, her hand in his.
"Brother, did anything happen at school today?"
"No, nothing special."
She looked at him. "Really? You're not lying to me, right?"
"Of course not."
She smiled, but there was something in her eyes... something deeper.
"Brother, can you promise me something?"
"What?"
"Promise me you'll never leave me. Even if you fall in love with a girl, or get married, or anything... you won't leave me."
Her voice was deadly serious.
"Of course I won't leave you. You're my sister."
"No!" She suddenly stopped. She looked at him, her eyes gleaming. "Not just my sister. I... I'm the most important person in your life, right?"
[Warning! Attachment Level = 95%!]
[Critical Situation! Choose your words carefully!]
He knelt down to be at her eye level. "Mi, you are the most important person in my life. I'll never leave you. That's a promise."
Her eyes filled with tears. "Really?"
"Really."
She hugged him tightly. "I love you, brother. I love you more than anything in the world."
"I love you too, Mi."
They resumed walking. But Lin Chen noticed something.
Her hand... was holding his with unnatural strength. As if she was afraid of losing him.
[System: Congratulations, you have gained your sister's complete loyalty]
[But beware... Complete loyalty from a Yandere personality can be a double-edged sword]
He looked at the sky.
"What have I gotten myself into..."
But at the same time, he felt something warm in his heart.
At least now he had a family. Someone who loved him, protected him, cared for him.
And he would protect her... no matter the cost.
