Sooyoung, Seohyun, Yuri, Jessica

YulSooSeoSic is the closest to her I think.

for before I think it's Yul
but now I think she's close with Sica mais ^^

No doubt it's Jessica ^^
YoonSic <333

at the moment, it's Sooyoung
then Sica

Yuri, not anymore

Its Yuri, I think. Yuri and Sooyoung. If you watch Hello Baby where theres Yuri in it, she always whines and wants Yoona to be with her. Idk about Yoona but Yuri really likes Yoona.

Sooyoung was Yoona's debut friend, and then came Yuri. They were best friends in their trainee days.

To put in ranking-

1. Yuri

2. Jessica

3. Seohyun

4. Sooyoung

5. Taeyeon

6. Sunny

7. Hyoyeon

8. Tiffany

This is just my ranking so don't think about it too much but i think they are all near to each other
