In 171202 MMA, Sana greeted IU and Joy (Red Velvet).

[There should be a GIF or video here. Update the app now to see it.]

(Update) In 180629, Sana and Joy were having fun together~

Some other moments:

- Sana & Yeri (Red Velvet) hugged when they performed "Into the New World" together.

- Sana played IU's and Red Velvet's songs in her solo V live and said she loved their songs.

- Yeri (Red Velvet) mentioned that Sana gave her a nickname (MingMing)

They're so cute! Seems like Sana are friends with Yeri and Joy already, so I hope her and IU would become closer in the future as well! <3
