characters like this mc are so frustrating

they see all the red flags but are so blinded by their "feelings" or whatever that they CHOOSE to be stupid and naive. Some of you are calling Soobin "sus" when blondie is the one being annoying and doing whatever he wants. Sure Soobin may have feelings for mc too, but doesn't make him a bad guy or "sus". Its not a crime to like someone, and so far all I'm seeing is him looking out for his friend. he hasn't hurt mc nor has he lied to him or manipulated him. He's just telling him that blondie is known to sleep around and maybe it's best to keep things strictly business, which are all true.
