Hatano

Hatano is downright uninterested in school until the object of his obsessive and unrequited love, Hikari, visits for the summers. He has excessive energy that verges on annoyance; routinely addressing Nanami and Kenji as a married couple, he always exasperates and flusters the pair. Conflicting with Hatano's infatuation for Hikari, his immature nature profoundly infuriates her and unknowingly ruins the plans for advancing Nanami and Kenji's relationship.
