On December 20, GFRIEND's management agency SOURCE MUSIC uploaded a new video on their YouTube.
The video was of YERIN at backstage with JOY before and after Red Velvet's most recent concert 'La Rouge' in Seoul.

Following that, YERIN told JOY, "Well, I'm going to turn the camera off and go now."
As soon as JOY heard this, she hurriedly grabbed YERIN's camera and said, "What? You didn't even film me much at all. Film more of me!"

YERIN took a look at JOY's overall appearance and said, "You remind me of a rose? Am I right?"
JOY gave YERIN a big hug and said, "Yes, you are!"

JOY responded, "I didn't cry on stage at all, but I ended up crying after I came down from it."
Then, YERIN commented, "You looked gorgeous during the concert, by the way. You really looked like a beautiful rose."
JOY smiled ear to ear and said, "Awww! Thank you!"
