Jiwon is stupid... He went and slept with someone who recognized him from his birthmark and body alone.. Moreover he even gave the backstory of it.. He knew everything that was out there to know about BJ alex.. That's borderline fan boy/ stalkerish.. Nobody sleeps with their stalker and says this is just physical don't get attached! ╮( ̄▽ ̄)╭
but some readers should expect this kind of behavior from alex since he did told dg that he isn‘t interested in a relationship (chap 8), so alex actually doesn’t has to expect anything more than sex from dg. It was the deal which both of them approved.
It couldn’t hurt being nicer to dg tho but dg srsly needs to start growing some balls

One: Jiwon was very clear that their relationship was just sexual. Jiwon isn't obligated to give his time to DG.
Two: what the fUCK?!? Could you be any more of a dick towards DG I stg if you make him cry I will lose it. I hope your vape breaks.
