At first, I suspect the stalker is Glen. But The Prof action also suspicious. So I dont like both of them. Accidentally I read that in the end MC will choose to be with (XXX). I'mma so mad, because In my eyes Vincent should be the one MC choose T_T (Ah, I regret how I found the spoiler that I didn't want to know before by accident) But, It's okay maybe In the next chapter Glen or The Prof will change my mind.
It's obvious actually, otherwise the title wouldn't be Glen. Unless this author intending to make a plot twist and out of the box ending..but usually BL manhwas aren't that complicated. I know that Vincent will just stay as friends in the end, it doesn't seem like the author intending to bring out the love triangle feels anyway...maybe just a one-sided crush on him.











I'd rather wish MC end up with Kihoon.
He's the type of tsundere, but will treat His lover gently
