Ohh okay so it was the brother! I kept thinking it was the ML but I was like wait they’re 2 years apart, but maybe Ideum was held back a year because of his heart condition/surgery but I’d think atleast one of them would figure it out if they were classmates but if it was his brother, that makes more sense. Aww what if the brother had a little crush on ideum too but he didn’t act on it since they were so different and obviously both guys

if ever the brother of the seme is the first love of the uke, the brother is 29 and the uke is 26 HAHAHHAHAHA how can they be classmates (or the brother just started school late ) i just want the brother to appear if ever he is really the first love/classmate
