Most Likely
1. Shuhua
2. Miyeon
3. Minnie
4. Soojin
5. Yuqi
6. Soyeon
Least Likely
Shuhua & Miyeon : Since Shuhua and Miyeon are REALLY clingy, I think they would also be into skinship and cling to their s/o a lot.
Minnie & Soojin : These two probably like skinship as well but wouldn't be as much into it as Shuhua and Miyeon.
Yuqi & Soyeon : I think these two don't dislike skinship but keep it a bit on the low in comparison to the other girls.
