Isshou Hatarakitakunai Ore ga Classmate no Daininki Idol ni Natsukaretara

Rintaro Shido, a high school boy who aspires to become a full-time house-husband, is in the same class with Rei Otosaki, a popular and well-known idol. The two have no relationship other than being classmates, but that changes drastically when Rintaro serves Rei a home-cooked meal after she nearly collapses from hunger! The food was so delicious that Rei asks him, "Can I come and eat with you every day?"
