Thanks for this. Cuz I was like whomst?
Finally found someone with common sense to realise that in no way is that bully ever going to be 2nd ml.
If anything, considering how that bully was somehow connected to juheon's aunt (i think that's the person he had a drink with), he's gonna be a common enemy. Definitely not a 2nd ml.
A creep towards either Dohu or Juheon? Maybe, that too is ever so slightly possible though idt it'll happen cause as previously shown, that mf is a toxic homophobic straight person.
I think most people simply don't remember who the bully is. If you reread the part where he appeared, you would be crazy to want such a terrible person to be close to either Dohu or Juheon.
Also, second love interest is an overdone trope that usually used to invoke jealousy. A lot of people want that to happen as if that's the solution to Dohu and Juheon relationship. Personally, I feel the bully's role is to cause problems. Rather than jealousy, I see him invoking Dohu and Juheon protectiveness for each other. Even when they are apart, they both still care deeply for each other well being.
A few interesting stuff foreshadowed here. Dohu has been taking medicine to fall asleep, and it doesn't seem to help his fatigue, so it's a matter of time before he collapses.
Also, Juheon has dyed his hair black before. It's likely that he had persistent stalking problem long before he encountered Dohu, which is why he was even more on guard when dealing with Dohu, likely superimposing Dohu with his other stalkers. He decided to go back to acting for reasons yet specified.
Finally, the bully is back and still pretending to be chummy with Dohu again. Unlike many, I don't think the bully will be the second love interest. Dohu would never entertain that. However, I can see him talking crap about Dohu for everyone in the party to hear, including Juheon.
Lots of stuff being set up. I'm curious how it will all go.
