I’m currently reading “anata ga shitekurenakute mo” and “soredemo ai o chikaimasu ka” and I’m obsessed. Are there any other works like these? I like the perspective of older female like these ones. It doesn’t have to be about a failing marriage, can be others but where the female lead is in her 30s/40s.

Toukyou Tarareba Musume - this manga is all about being in one’s thirties. Age is the focus, there’s not much of a romance.

Udon no Onna is good, mid-30s divorced protagonist.

10, 20, and 30 maybe, I haven’t read it yet though.
