HE! Wei Yuran and Gu Liubai met in their second year of high school. The two disliked each other at first, but by mistake, Gu Liubai lived in Wei Yuran's house and began their cohabitation life of "love each other"... They originally thought that they could be roommates, classmates, and good friends at most, but they accidentally turned into lovers? The story about the gentle and loyal dog Gong and the withdrawn and arrogant person is not a pure sweet story. It is more about the growth of two teenagers and the growth, tolerance and acceptance of a family.
