Korra’s side chick's Questions (3)

Does anyone have manhwa reccs where the ml or fl is like way older than the mc or like the mc’s mental age is over 30 like the love interest of they transmigrated?? Ill take BL’s, GL’s and regular romance ლ(´ڡ`ლ)

I read this comic over like 2 or 3 years ago and can barely remember it, but I know the comic is in black and white, the mc is a girl with black messy hair, and I think her blowers are blue or red (I think), she went up against these generals or smth. I rlly can’t remember （/TДT)/ I’d appreciate if someone found it

I suddenly remembered this out of no where but the plot was like the uke was a bdsm trainer who would train subs to be auctioned off to doms. (as far as I can tell he spanked them) And he wanted to experience that too but felt as if he couldn’t, then the ml comes and gain interest in the mc bc of his build and they (yk) in some closet and more I can’t remember. Pls help find it ٩(๑❛ᴗ❛๑)۶
