Akomi's boyfriend is catastrophically stupid and somehow that's the whole point. The joke isn't that she tolerates him, it's that she genuinely loves him anyway, and the show cranks the comedy so fast you don't have time to think about whether any of this makes sense. Five minutes has never felt shorter.
Akomi is dating Ponta Ninomiya, a boyfriend who is extremely good looking and, apart from that, an utter fool with nothing else going for him. Yet he remains her boyfriend. Across eight episodes, this gag-driven romantic comedy is built around the pair's ordinary day-to-day life together, with the humor coming from his stupidity and the relationship that somehow survives it.
