he IS toxic and immature but like he at least has a good reason to be bc we know his pov unlike hyuk. AND his bf is literally enabling him/tolerates his behavior. thus, most readers would tolerate him too.
personally, hyuk is stupid. bro liked mc since middle school, didnt shoot his shot, and is now trying to wreck his bsfs rs?? nah leave them alone, but ofc he cant bc plot and character development for seme bc all they do is fuck like that's gonna help with his insecurity

Y are people not hating on the seme? He is so toxic and immature its crazy annoying
