There was an extra earlier in the series where a very similar scenario played out.
Either way, I hate this. I absolutely fucking hate this. If only Jaehoon had found out and shamed him. He would have put an absolute end these attention starved shenanigans. Damn Soorim with his nice guy bullshit, letting his dumbest and most vulnerable friend show thigh to a bunch of pedos for NOTHING. White cat Hooni is so cursed. This entire arc is like a dark abyss.
