U kinda can tell what will happen with the opening song and ending song. Its like a big spoiler.

He survived.

Theres not much to say, are 2 sides in this website "FL is a cheater" and "FL is not a cheater". No side will backdown so its useless even to talk about that in this point. Until now, great show, ML character was well made and his dialogue was right on point like in the novel.

HE, FL never cheated nor regret get married with ML, next episode should be when ML understand that. No one dies of the main cast.

For what I see of FL, she will reject the divorce.

This. I'm sure, all the haters are probably teens or people that already got betrayed for a significant one.

This part didn't happen in the novel. I think before the last showdown, they will probably change the end.

noble idiocy trope

Main Villain is focusing on her because of ML. ML is trying to distance himself of her.

Right after

Yes. There's some flashbacks. It's even better if u don't watch PA.

Male Lead

With ML

ML is a "genius", FL is just a rookie inspector.

No, but he will move himself eventually. No, like I said, FL just see 2ml as a shadow of her past, maybe doesn't seems like it, but she already move on in terms of love with 2ml, now she is just worries about him as a old friend.

It's doesn't happen.

Yes

Husband, it's a marriage first, love second, however until the end 2ml will have no chance, in FL pov 2ml it's just a shadow of her past.

HE. No one dies.

They end up together, 1 year later. Before she goes, they make a promise that, when she is ready to be with him in the future she would come back.
