While To Heart and KimiKiss differ in their plot structures, both are primarily interaction driven and could be considered to be different takes on portraying the possibilities that the relationship between childhood friends hold. Note that both are non-harem romance anime set in a school setting, exploring about 1 year in the central characters' highschool lives.
To Heart is much more subtle than KimiKiss but chooses to focus on being a slice of life show while KimiKiss uses plot drama and gentle slice of life nods, to tell a romance.
