The story has potential to be much more decent if there was more to it. It ended in a way that makes you think there's got to be a sequel coming bc there's hardly any proper closure. It's almost not worth reading to just have it end like that.
Another cmmt has their relationship wrong. Hwan and Chiwoo technically still don't end up together bc Hwan wants to work on himself to become a better man before getting into a relationship with Chiwoo. But Chiwoo was attracted to him when they meet again in the new timeline(?). He asked Hwan out but Hwan rejected him bc of the prior reasons I wrote.
At the end, they've been friends for about a month in this new timeline, and Jin is reintroduced (I think he's real now, maybe? Idk, bc Moony is also around and is hinted to have messed with Hwan's life too), with Chiwoo calling him handsome. And that's it. Tho the end does hints that Hwan is handling his feelings of jealousy better.
The new timeline, that happened bc Chiwoo sacrificed himself to save Hwan, does relatively well in giving Hwan a redemption arc, but it's so rushed and is unsatisfying in how open-ended their relationship is. But what absolutely sucks is that Chiwoo has no memories of any of the original timeline whatsoever.
It's like we, the readers, lost the main character (the new timeline is largely told from Hwan's POV). It feels really unfair that the Chiwoo who suffered had to disappear in order to become happy/content with his life.
And then there's Sunny (and Moony) starting this whole magical boy ordeal with a completely new character, whom we don't see anything more abt.
I just feel like this series needs a sequel bc the way it ended could only be satisfying if the author was planning for one.
It's good for the smut if you're looking for that, esp with a fresh concept (the whole magical boy thing). It's not a bad story but it can be frustrating, particularly if not having proper closure bothers you.
Also, beware 2nd ML syndrome (tho the open end may give you a little hope if that's how you want to interpret things).
