Yoona, ofc. She has many films. When I watch the last episode of You're my destiny, I cry. In that drama, her mother died so she cries a lot that makes me cry and sad
I think Yoona is good and has a wider grasp in uigizaji but she's not that good in on the spot acting. I think Sooyoung is the best and Jessica is good too. I realized in Hello Baby when they decided that they should act that they are fighting in Seohyun's birthday to surprise her.
