OMGOMGOMGOMGOMG THIS IS JUST A THEORY BUT I WENT BACK TO CHAPTER ONE.. WHAT IF HAESOO'S EX KS THE STALKER?? IF YOU REMEMBER THAT GUY WAS SOOOO HUNG UP ON HAESOO

I don't know the exact chapters, but the first time we saw that stalker was in the club with Leo. After we saw him in a flashback, with Haesoo in a bookstore. There we saw Taku too. The stalker is more interested in getting back with Haesoo than finding some evidence that J and H have something going on.
We still haven't caught up to the very first chapter of the story either, at least I don't think.. but I believe we're close!
