Gekkouzaka no Hanayashiki

Kashiwagi Yukiya shares a family home with his son, Yuuto, in a mansion passed down from his grandparents, located near blooming trees. Another resident is Takanashi, who remained after the house transitioned from a student dormitory to a private residence. He continues to live there due to its proximity to his workplace and his feelings for Yukiya, whom he is eager to understand better.
