Hyeri quietly walked into ROSÉ's waiting room, singing a celebration song.

At the end of the song, ROSÉ commented, "Unnie, what is all this? The cake looks delicious! Thank you so much!"
Then, Hyeri and ROSÉ sat down and ate the cake and just-delivered pizza together.
Previously, it was revealed that Hyeri and ROSÉ became close after exchanging their phone number during the shooting of tvN's television show 'Amazing Saturday'.
