Some might not exactly be what you're looking for but hope you like it
I like that the main couple are already established in their relationship (both are mature as well, FL is not brain-dead with love). I dislike unnecessary drama like, the guy or girl being unsure about who they really like and such (no more love triangle shyt). What I like about this is that both main characters are sure that they love each other and no prolonged chapters or arc before they get together.
