Please recommend nice romance anime that doesn't significantly involve
>love triangle or haram bs
>drama over ex-bf or ex-gf
>cheating or temptation to cheat
and similar stuff as a significant plot point. I want to watch something comfy where it's centered on just the couple themselves and doesn't drag other people into the romance as sources of issues. Working through other types of conflict in the relationship is cool I'm just tired of the aforementioned tropes where there's big drama over some third party. I'd like to see something that focuses more on the couple's dynamic with each other and how they grow together. Thanks for any suggestions!
