I just dont have anything to like about her (personality/characteristics wise). Aside from liking strawberries, being cute, and a VERY skilled performer, there's nothing else I know about her. I'm not saying she has no personality/good characteristics, but I just dont know it. All I see is an ace idol, and aside from being idol-like, I dont see a "Karin the person" behind "Karin the idol".
Unlike, say, Tomoko, the quick talking bully lol or Aarii, who's shown her funny side in photos and backstage footage and the like. Even Yuka, who likes space(?) and doing announcements, and is shy/timid type.
So yeah, I do admit about having the whole "ace gets all attention, give the other girls a chance" mentality, but its not the reason I dont particularly have much interest in Karin. I do like her performance/expressions though.
