|This is pretty much ALL spoiler so...
Spoiler (highlight to view)
Habaek's fated person is Soah! (Yay! :D I was always Team Soah! ^^) When the old man told him that the person who he was thinking about isn't his fated person, he was lying. He said so in a different chapter. (I forgot the exact reason but I do remember it helped him and Soah get together.)
This pretty much all happened recently so if you didn't read about this, go check it out!
