Shuhua is in love with Miyeon. Miyeon is engaged to Minnie. Yuqi is in love with Minnie. Soojin is in love with Shuhua. Soyeon is in love with Soojin. Basically these lovesick fools played a game of musical partners. 

Note: I wrote a story a few years back that was Snsd Yoonyul. I've thought about rewriting it for a while as it wasn't as long as detailed as I'd like and I want to give you all something good to read. At it's core it's the same story. Everyone is confused who they belong with. But it definitely got way more angsty than intended. But I promise everyone is happy in the end.
