I had a big NO moment at the end there LOL. That’s how you know a series has me quite ensnared.
Anyways, this might just be one of those tension cliffhanger types. I trust yuri’s character a lot based on what we’ve seen already so I’ll stick to trust that until we get a complete picture. Perhaps she just hates sung ah for a lot of different reasons particularly with regards to Junwoo or don’t want to get on the wrong side of girl bullies. Either way, this is yet another interesting situation.
