Rui'er and Shuishui are close friends, but unfortunately Shui Shui has violent tendencies, which makes Rui'er often attacked by Shuishui's "pink punch".
Shuishui doesn't have many boy friends because of her violence. But she fell in love with Mo Ziyang, a boy in her senior year of high school, at first sight. Rui'er wanted to take advantage of this to blackmail and make fun of Shuishui in order to avenge herself, but things didn't seem to develop as she expected... Things made her a little overwhelmed. After all, Shuishui was still her friend... ^_^
