Forgot the title

I want to reread a series but forgot the title. It's a love comedy set in a high school. The MC has to tutor these girls who are super talented in certain areas but don't want careers out of their talents so the teachers left them to the MC in the hopes he would talk them out of their dreams that are the opposite of their talents. One girl is like super skilled in stem stuff but has almost no social skills and wants to study psychology and create board games and another who is a brilliant author but wants to study astronomy because of her mother. There's also a childhood friend who is a swimmer and needs tutoring in languages to go over seas and a teacher who was a former ice skater. Each heroine got a version of an ending and the endings had names like the bronze mermaid and tabletop thumbelina?
