A pair of enemies, real enemies. Take surnames as an example. One is named Yu, but the other is named She. As for temperament, one is as cold as water, while the other is as passionate as fire. As for preferences, there are many differences. One never refuses to eat dessert, and the other is the owner of the coffee shop. What about the nicknames... One is fish and the other... Is cat? "No, I think it's a tigress!" He said angrily to himself. She seems innocent and harmless, but she is actually a "martial arts master" whose agility is breathtaking. Thinking of the way she practices boxing, uh... It's a little scary? However, he still couldn't help but want to know how many things he didn't know were packed in her little head. She seems innocent and as simple as a child, but she actually has a lot of tricks up her sleeve. The countless weird ideas drove him almost crazy.
