System Sister Is so Cute

"Do you want to understand the meaning of life? Do you want to really... Fall in love?" "Talk about your sister." "It's not impossible..." "Huh?" In front of the desk, Jiang Yu was trying hard to think about a high-level math problem, when a voice suddenly appeared in his mind. He thought he had been doing the questions for too long and his brain was spinning. Other side. Love system. System Ji clenched her fists, and for the sake of performance, she decided to do a small cheat. She secretly transformed into a human body and lied that she was her sister. It's all about falling in love anyway, who is it different from? Talk to the system... It should be the same... Should?
