Does yuri actually like glasses? I've been speculating that they were pretending to cheat for a while now. It's confirmed in this chapter that they're cheating, but I'm still tryna theorize n shit. A cheating scandal is way too simple, and yuri's character doesn't seem 1 dimensional enough where she would stupidly fall for glasses. It's weird cuz yuri and her partners attitude are so different compared to the other couples in the show.
Yuri seems smart and cunning/sly compared to Joo-ah who's more naive, that's the main reason why I think she's pretending.
