Wasted potential.
I feel so bad. I was really excited about this one and I liked it, to an extent, some of it was done so well. But then they dealt with a few things so ridiculously it really ruined the experience.
First off, if you introduce a character that is supposed to be the male leads best friend and you show that love and you start caring for them and then you harm the character just so the hero can get to be emotional that's fine, nothing wrong with that. But what does it say about your main lead when literally the very next episode the writers forgot he even existed!
And they show Hui Young's TRAUMATIC life but not ONE single 'friend' ever so much as sympathizes with him or shows empathy! But they're quick to see him as the villain when he does things out of desperation.

Basically everything they set up in the beginning, they ruined it and suddenly a nuanced good script was becoming boring and bland.

So by far, we have a main lead who found a girl and forgot his childhood friend and isn't the least bit affected by what happened to him! When he was practically the only friend he had since they were kids ffs!

And then the female lead again, even when she found out about hui young and what happened she's only worried about the new shiny guy she JUST met and doesn't feel ANYTHING for Hwi young who again, they've been friends since childhood!
Do either of these characters seem not selfish to you?

And no one among the writers seems to have ANY FREAKING CLUE what trauma is. Obviously, they were trying to be edgy but ended up writing extremely shallow characters. And don't even get me started on how they handled Moonbins character! Ugh. Just probably added that bit for edgy brownie points and it went nowhere and was completely pointless!

A disappointment but did give me some entertainment hence the rating. The actors definitely deserved better.
