I'm also projecting lolol

I just read up to ch7 and he's just actively thinking about wanting to sleep with an engaged man, hoping the marriage is called off, he's also super jealous of Gisella, and just being all kinds of frustrating. When he said in ch1 or two that he thought Sejin would only have him around for the rest of his life I was like ???? You never even confessed wtf are you talking about
Definitely one of the most annoying mcs

I think thats normal. Wishing it was you instead of him/her, that's because you like them. But as long as he isn't commiting the act wishful thinking is okay. Just keep to yourself. Humans aint saint

I've read more than ch7.

I've read more than ch7 but dropped this cuz update was slow. So im not sure if in later chapter they cheated.

I think people do have those kinds of thoughts at some point in their life, When someone they love gets with someone else before they even have a chance to confess their love. I think that the way the MC handled it was better than most do, he kept it to himself and he moved away on top of that, Probably to be able to contain it better and that's a whole lot better than being a homewrecker. What happened after that was due to the ML being clingy and the fiance seeing the obvious feelings that were there, Deciding that she didn't want to brush it under the covers before she got married.

u just can't stand realistic MC's do u? did the mc actually slept with the ml who has a fiance? Is it so bad to be jealous of someone who holds the heart of the one u like? r u being serious??
