After My Girlfriend Betrayed Me, I Turned and Took the Campus Belle's Hand

My girlfriend agreed to be Xu Xinzhe's girlfriend for a month to help her childhood sweetheart save face, and to fulfill all her girlfriendly duties. When they were fulfilling their duty to kiss, I angrily broke up with her, but she couldn't have cared less. “Don't be such a sore loser. You're acting like some old-fashioned fossil. How embarrassing!” Not wanting to embarrass her, I joined the game too. My task: win the school beauty's first kiss! Just as everyone was laughing at me, the school beauty suddenly kissed me. “Your task is complete. Now it's my turn, boyfriend for a month. You have to fulfill your duties, okay?”
