Aisare Tenshi na Classmate ga, Ore ni Dake Itazura ni Hohoemu

Ichise Soma is a high school boy who dreams of becoming a pastry chef. One day, he shared some of the desserts he made with his classmate Chika Satomi. Chika is a pure, beautiful girl who is known as "the angel of grace" around the school. He thought she would just say something nice and polite about his desserts, but she showed a surprising side of her personality when they were alone together, and it's getting him all flustered! It's a sweet and exciting boy-meets-girl story with a naughty angel who loves desserts!
