Tsukuyomi-kun no Kindan Oyashoku

Overview

During the day, she is the "goddess of beauty," a personal trainer inspiring others to get better. But at night, after work, she gets hungry and down on herself. That's when the handsome but mysterious young man Tsukiyomi-kun appears to cook her a meal that fills her up and heals her soul, even though they've signed a contract that banned any romantic feelings between them. It's a sweet forbidden gourmet love-comedy between two people! (Source: BeLove, translated)
