3)she can improve the mood in any situation
2nd would be Nicole
1)Not really sure..but sheget confused for no reason
2)very friendly and approachable

She has the talent in variety shows as proven in IY..Would definitely like to see her to be a guest in shows like Family Outing since it's somewhat similar like IY
