OK so I've been watching alot of AOA mv's lately and it seems like Choa and Seolhyun are paired together frequently. So with their new mv as a base plot, I'm thinking of a new girl (Seolhyun) transferring and she joins their team and helps Choa who is crushing on the rival. But then Seolhyun develops feeling for her and is becoming reluctant in helping her. Does this seem like a good story line?
