Together, they play strange games, go on spontaneous journeys, crack silly jokes, and celebrate each other's successes. However, each individual must also deal with their own issues, whether it is struggling to meet a deadline or coming to terms with traumatic events buried in their past. [Written by MAL Rewrite]

Hated by everyone around him, Sei Handa goes about his high school life regarded as an outcast—or at least that's what he believes. In reality, Sei is the most popular student on campus, revered by all for his incomparable calligraphy skills, good looks, and cool personality. However, due an endless series of misunderstandings, Handa perceives the worship he receives from his legions of fans as bullying, leading the school's idol to shut himself off from the rest of his classmates. But distancing himself from his peers doesn't deter them from adoring him; in fact, his attempts at drawing attention away from himself often end up unintentionally converting even the most skeptical of students into believers. Fashion models, shut-in delinquents, obsessive fangirls, and more—none can stand against the brilliance that is Sei Handa. [Written by MAL Rewrite]
