Uyu's Questions (5)

So I'm trying to find this manhwa about a woman (brown haired I think?) and she's an "extra" or just an NPC in the story (she's not meant to be with the male lead is what I'm saying). Anyway, this husband of hers (blonde guy and male lead of the story) returns after years I think but he brings home with him this "strange woman" (red hair) whom is the "female lead" or the story. He claims that she's not someone special and is just a relative but it turns out they're secretly involved with each other. One day, our female lead caught them kissing and after that she decides to run away from the male lead wherein she left just a letter (saying that they're over I think and wishing them well?) and her wedding ring on a nightstand and she goes home to her family. I don't know the title, please help me.

I want to look/read a story about the seme being a jerk/scum, tells the uke that he doesn't want a romantic relationship but in the end begs the uke to give him a chance when he finally realized his feelings for the uke, the uke is trying to move on or something and the seme suddenly chases after him(?) Something like that. Or any stories with the similar theme where the seme suffers for being a jerkwad
(. ❛ ᴗ ❛.) THANK YOUU

I'm looking for a manga where the seme and uke has a really good relationship, they love each other, all the good shit, until the seme, one day, says that he's going to get married to someone else...

Manga recommendations where uke truly loves seme but seme treats uke like a toy or a sex partner until uke gives up and later on seme realizes his true feelings and chases after the uke

Any recommendations where seme bullies uke until uke decides he wants to die but is still saved by seme (can be that the seme is the only who bullies the uke or the seme bullies uke like everyone else).
