"But I HAVE to tell him" No. No you don't babe. The second you hear he's dating is the second you turn that lil crush off. It's called respect, learn it
I know he did not just tell Dohu to QUIT his JOB just cause it's a wittle awkward for wittle baby Juheon... Bro quit ur job if it's so unbearable, why jeopardize ur ex's career cause ur piss hurt?
