Be Good, or I'll Make You Die

Cheng Yan was a beauty with an icy, untouchable aura. She was an excellent student, gorgeous, and destined to attend Wudaokou Vocational and Technical School. Then one day, a tenant who needed tutoring suddenly moved into her home. The tenant seemed incredibly well-behaved, but was actually an expert at throwing tantrums, rolling around, and pleading shamelessly. After Cheng Yan confiscated her little yuri manga for the Nth time, the girl grinned and pinned Cheng Yan into a corner, saying sweetly, "Yan Yan, if you want to borrow my manga, just say so. Isn't it a hassle to keep confiscating it back and forth?" Cheng Yan lowered her eyes and looked at her. "The manga gets it wrong." "What's wrong about it?" "Want to know?" Cheng Yan chuckled, then spun her around and pinned her against the wall. "Then call me 'big sister' and let me hear it." Yu Wen immediately grabbed Cheng Yan's hand. "Big sister, dearest big sister, tell me, please." Yu Wen loved playing video games. One day, her friends noticed that as soon as school let out, she went straight home and never went anywhere else. They asked what she was going home to do. Yu Wen replied helplessly, "Tutoring and homework." Everyone burst out laughing. "What, are you scared of the teacher?" "Who'd be scared of a teacher?" Yu Wen was about to deny it when a chill suddenly crept up her back. "...Uh, I'm scared of my wife." 1. Couple: an aloof, untouchable beauty X a shameless troublemaker. 2. Happy ending; they reunite after a breakup. 3. Both of them are already adults when they first meet. Adults, adults, adults. This is an uplifting story, and both of them get into university.
