家事代行のアルバイトを始めたら学園一の美少女の家族に気に入られちゃいました。

by Shiohon

During the summer vacation of his second year in high school, Harusho Ootsuki started a part-time job as a housekeeper. To his surprise, his first client is Ayaka Tojo, the most beautiful girl in the school! As he performs his duties as a housekeeper, Ayaka's family takes a liking to him, and he begins to spend more time at her house. The two grow closer as he makes Ayaka happy with home-cooked meals, they go to the supermarket together like newlyweds, and go see a movie like a first date. This is the start of a frustratingly shy romantic comedy between the most beautiful girl in the school and a hidden high-spec boy! (Source: GA Bunko, translated)
