Ririka's so young that at that age she could like something one day and be totally disinterested the next day, but considering she was there to play against Chihaya in the first place, and how those people wondered if she could develop into another potential Queen, she must have shown some good results in the past. I don't think she could have achieved that without determination, that is, liking what she's doing. If it originates from turning a weakness into a strength doesn't matter; everybody has their own way of finding their best hobby.
