I watch a lot of romance animes, but i miss super down to earth realistic relationships like,
Sword art online (post marriage life),
My teen romantic comedy (unhealthy attachment styles),
maybe Bunny girl senpai (because we see so little growth and time of them together)
Classroom of the elite (How relationship isn't the main objective of the Mc's life, if we put aside the fact that he has no feelings for her at all)

I don't want to see a idealistic relationship, I want to see a strong couple facing life, and relationship problem and learn to grow, change and develop into something beautiful.
