I've done some research and this really seems to be the end?
Honestly, it's quite a good story, even if it's true that it all seems to be very idealized (I wouldn't know how to describe it but hey)? Some say it's cringe, but it's not at all? I think they have a really cute relationship! Especially for Sunghoon who has never been in love, it's normal that he doesn't know how to take it (even if they seem to be a gangster? especially the moment of Seoyu's ex in front of his house... I would have liked that this side of him is more explained). In fact, if I think about it carefully, there are several things that could have made this story better (memory of how Seoyu experienced the death of his parents, what his uncle did (but maybe I was not paying attention correctly and didn't understand what he has done) or else obviously seeing their child at the end especially since he's on the cover) but it's still well done in itself!
It's funny to see how we judge a story when we wouldn't necessarily be able to do the same lol. ╮( ̄▽ ̄)╭
