Jung ChaeYeon and Jeon SoMi were members of I.O.I from Produce 101 Season 1. They moved on with their own ways after the group was disbanded, as ChaeYeon is now in group DIA and SoMi in Unnies (did not debut formally yet).
It's been quite a long time since they spent time together or even seen each other. Recently, two of them greeting each other so dearly was caught on fan's camera on the way to Music Bank.
Look how happy ChaeYeon looks when she spotted SoMi!
She runs to her like a adorable puppy, and SoMi looking so happy when she hugs her.. So adorable.
There are still fans of I.O,I who wished 11 of them would get together and perform for even a short time or do collaborations, however, there is no news about it yet.
