Now it kind of makes sense why Doyun is refusing to accept that he likes Taehan. I think the older brother could pass for Taehan's twin! Maybe Doyun has always had a secret crush on his brother?
I honestly think she's in on it. I'm convinced she'll be the next 'victim' and Jinyoo will try and protect her by taking her place, and then afterwards she'll turn around like... LOL SYKE we played you for a fool.
and YOU MOTHERFUCKER are dead
