Adapted from the Korean comic of the same name, it tells the story of Mizunase Jin (played by Motojima Junzheng), an excellent student who is indifferent to others. For the first time, he lives a student life in order not to get involved with the problem child in the class, Hirikawa Haruki (played by Uemura Kenshin). But one day, Mizunase accidentally saw Hirikawa beaten by his father outside the school. Mizunase accidentally knew the secret and kept his distance from Hirikawa in order to prevent the relationship from getting deeper, but the image of Hirikawa, which was completely different from that in school, lingered in his mind.
