Well, we learn that Cheol's 2 stalkers, while being rivals and hating each other, somehow reached an agreement during those 14years. Minyoung "delegated" Cheol's daily stalking to that Jaehee. Jaehee kept tabs on Cheol and shared it with Minyoung while Minyoung focused his efforts on his career. Don’t know if he paid for it or if that Jaehee was satisfied with Minyoung staying out of the picture.
And now Minyoung grabbed back on Cheol, he is telling Jaehee their deal is done so he might as well f*ck off as he was never anyone to Cheol to begin with.
This is so messed up ( ̄∇ ̄")

Ok, I think I’ve dumbed down during my holiday. can someone explain this chapter to me?
