Wait so the idol likes him back?
Whats the idols intention??
Well I don't want to spoil too much so you guys can enjoy, but! He approached the teacher on purpose. He's trying to make him fall for him so he can act on revenge for a friend. And it's all a huge misinterpretation from the idol and said friend. (This is a little further into the plot btw)
do you have a link to the raws?hahaha
Wait act for revenge for the friend? Was he in love with the friend? What happened? You can spoil me
Sadly I don't, but it was in back in the comments somewhere. It's been some time thought!
Apparently the friend of the Siyeol likes the other member of the group (the one who's cousin of the mc or something) and thinks the teacher and that other idol (I mean the tan one fyi) have something going on, so when they told Siyeol, he came up with that plan to seduce him, etc.
Sorry if you're you don't understand, I kind of forgot their names.
