It's a long summer and Byul needs something to kill time.  Little she knows that creating a YouTube channel could change her life this much. 

Byul meets Yongsun through an online application. They exchange daily messages but never have seen each other in real life.  Chapter one: a sad ending. Chapter two: a happy ending. 

Yongsun is dragged to the club to forget. In here she learns how to. 

Yongsun has a crash against a motorcycle. Out of pity and responsibility, she takes in the injured girl, takes care of her. 

Just Byul and Yongsun being cute and domestic. 

Wheein is fed up with her unnies fighting the fact that soul-mates or not, they love each other, so she makes it her mission to help them find the happiness they deserve with each others. Hyejin migh disagree with her methods but has to admit that it's nice not to have to listen to them mopping and pinning again. 

Byul and Yongsun have been sharing a flat for years but the contract is over and they need to decide if they want to continue living together or to move on their separate ways.
