wait hold up. why is he asking if jiho's gay? i thought they were a thing in the past?? aren't they?
Oh yeah. You’re right. But since Jiho once mentioned that the next time he fell in love he’ll be sure to confess properly makes me think the thing between him and Hyundai was just a super close relationship or a fling with no string attached. Just my interpretation. But still Hyundai is weird enough to still be asking if Jiho is gay though.
This is just me speculating, but I think Hyundo asked if he cheated because he and Jiho weren't in an official relationship. From Hyundo's perspective, him going out with other girls wouldn't be cheating because him and Jiho are only messing around. But from Jiho's perspective, he thought they had something more. It would explain why it sounded like his confession to Taeyeon was his first too.
OM THERE'S A SIDE STORY GUYS
