Except he didn't lie. They're legally married to each other. The way I would've pulled out the receipts

Well, I've never given them any "chances". It's a mafia story; not saying it's based on the truth but some irl stories of ex-mafia/gang/yakuza members are horror stories that are just much worse. Like the father who conditioned his daughter to sleep with other gang members/leaders for business relations, but somehow the bond between father and daughter is extremely tight but also messed up. Like he would kill anyone who hurt her but he also puts her in harms way and cut off her finger once.

I think for a lot of us normal people, we just can't comprehend fjckrd up stuff like this.
In Caesar and Leewon's case, honestly? Leewon has a powerful mafia father who would pull out all the arsenals to take down Caesar if Leewon just said the word. Caesar on the other hand needs a psychologist cuz he's obviously got a mental disorder of some kind. Their relationship is straight up toxic and it's not trying to be cutesy, although we all seem to forget sometimes with some light hearted/funny chapters.

It's a mafia relationship and the author is envisioning it as being the most toxic fxxed up shit ever and considering the context we can't even blame them. It's not like sa and violence is being normalized in the manhwa. It's definitely shown as being negative, but Leewon also has some kind of weird attachment/stockholm-esque love for Caesar for him to forgive him every time.
