Um...I don't think so. It brought me nothing but frustration. Didn't really like any of the characters there. Some people love it. Personally, I didn't. The heartbreak of Hanjun is plainly explained here anyway. Buuut, if you wanna read it, go ahead.
I feel like I'm not being fair so maybe wait for others to say something about it. I admit I'm far too biased about my dislike for the OG story.
So far no you won’t miss anything.
The main story is one of my fav i love it, it’s frustrating but lovely, it’s totally different than this vibe (the flashback is spoiler to the vibe of the main story)
It’s worth reading if you don’t mind (drama?)
Will i miss something if i did'nt read the main story??
