Tianyi has a melancholy personality and seems to be uninterested in anyone, while Silong has a lively and cheerful personality and likes to be clever. "I'll borrow my homework and copy it." This was the first time he talked to her, but she, who had always been an top student, gave him an unexpected answer: "I didn't do any homework." This made him change his attitude towards her, because what he couldn't stand the most was a good girl who pretended to be a good girl. Silong is indeed not well-behaved, he likes to be opportunistic and plays pranks.
