Man, I am baited by the cover. I thought it's going to be some epic battle manga
In a way, women's affairs ARE a battle...but yeah josei doesn't get too action-y tho a revenge scene might have more action/violence as opposed to just cheating/ sexual undertones
LOL I'm surprised karin would easily invite out to lunch/not be intimidated by her beauty or just expect to be a 'queen bee' again with MC following her
Always gotta have a snarky male side chara/potential love interest lol. and i know he's prolly tall/good to have a lot of coverage but even for a bartender his apron? seems a bit long on him, not that i've been to JP specific businesses but i think most male aprons i see on tv go slightly past the knees (tho the art style prolly gives him shoujo legs)
I doubt he likes her very much.
Affair aside i feel like a lot of bartenders can sense the 'mean girl/ex bully' aura from her if not end up 'disliking' a lot of customers hearing them pour their real selves out depending on how many drunks/complainers he gets
