A year ago, they met in University A due to "misfortune", and she pestered him to be her brother. A year later, her two-year secret love pantomime turned into tragedy, and he ended his five-year relationship with Qingmei. Meeting A again, they began their story. That day, she decided not to be a coward anymore. On the lonely and empty street late at night, she stood up on tiptoes to kiss his thin lips and said, "I don't want you to be my brother anymore." But the way he looked at her calmly made her timid. She turned around and wanted to run away. The next moment, he pulled him into his arms, deepening the kiss that she had given her before. After the kiss ended, she pushed him away shyly, "You are so skilled. You must have kissed your ex-girlfriend many times." He raised his eyebrows and said as if he wanted to be beaten, "I won't deny it." She said angrily, "Let's break up!" "We haven't even started talking yet." Angry Heartbroken, she gritted her teeth, "Let's break up our friendship!" "Okay." She turned around again, but was pulled into his arms again. He chuckled and whispered in her ear, "We've broken off our friendship, and we'll start a relationship as boyfriend and girlfriend."
