after google searching i just found out its not a dating sim like i thought but it has its own genre
genre: visual novel
is an interactive fiction game featuring mostly static graphics, usually with anime-style art. As the name might suggest, they resemble mixed-media novels or tableau vivant stage plays. Visual novels are commonly called dating sims in the West, a misnomer as visual novels are classified as a sub-genre of adventure games and not simulation games. This has led to confusion with the other genre known as dating sims, which often shares a similar visual format with visual novels, but has gameplay based on statistics.
