To Heart

Both happen to be slice of life anime with a male protagonist, who interacts with females, each having distinct character traits. Take Golden Boy, remove the ecchi, make the male protagonist a more serious person, capable of romance and finally domesticate it into a high school setting - voila! You have the skeletal plot, theme structure for To Heart. If you liked Golden Boy but felt the need for something more serious and possibly genuine direction, go for To Heart. On the other hand, if you liked To Heart and felt that you need something similar that is not constrained by a high school setting and coming-of-age romance, something more "otona", then check out Golden Boy!

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.
