When Hikigaya Hachiman, who calls himself a "lonely philosopher", meets Nohara Shinnosuke, a "dynamic agent" with out-of-the-box thinking and extraordinary mobility, the tranquility of the Sobu High School Service Club is completely broken. One uses self-destruction to protect others, one uses light waves to stir up daily life; one pursues "real things" at the risk of breaking up, and the other seems to be nonsense but speaks directly to people's hearts. Between Yukinoshita Yukino's poisonous tongue and Yuigahama Yui's gentleness, the youth story of four troubled boys and girls is destined to be full of problems from the beginning of their encounter. This is a story about twisted tenderness, clumsy growth, and finding the true bond between people in the most "dynamic" way.
