5-toubun no Hanayome ∬

The Nakano quintuplets are finally making academic progress under Fuutarou's tutoring, but studying is no longer the hardest part of their time together. He becomes more involved in the sisters' family troubles and personal choices, while several of them begin to see him as more than a teacher. At the same time, Fuutarou starts revisiting memories of a girl he met in Kyoto years ago and suspects that one of the quintuplets may be connected to that past. As graduation draws closer, exams and romance become increasingly difficult to keep separate.
