Looks like I'm gonna have to pretend the side stories don't exist then. Just the happy ending main story, yep. But also I wonder why the person who told you that keeps a tight lip about it. I mean, it's not like I can read the novel through official means even if I wanted to :| bc I for one don't speak Korean, and I highly doubt it's ever getting released in my country :| If I had to guess, I'd say one of them dies. Or Sa-Yan has to marry a woman.
