Just like what the title says!
Recently I've been reading How do we Relationship? And I genuinely think it's one of the better ones that I've read without a doubt. What I'm looking for is a Manga in which the story is not about "Will they end up together?" but more about an already established relationship and the struggles around it.
I'm looking for that and the very interesting themes of struggling with jealousy, relationship drama, perhaps even some toxic traits? Not mandatory, but the story being set in a more modern setting is quite appreciated.
The more mature vibe is also very much appreciated, so if you guys have any recs that fit those criteria I'd love to hear about it! (I haven't finished it yet, just about halfway, so no spoilers please <3)
