Under the spotlight everyone sees, our secret story begins.
The hottest idol groups in South Korea. LUA, a three-member girl group loved for their refreshing and sophisticated music. And VANTA, a three-member boy group beloved for their intense performances and unique aura. Both groups debuted in the same year, 20XX. Having established themselves as top-tier idols upon debut, the two groups often found their promotion periods overlapping. From music shows and award ceremonies to variety shows, commercial shoots, and overseas tours. As they crossed paths more frequently, they naturally became acquaintances who exchanged greetings, but it never went beyond that. At least, until now.

Month X, 20XX
With the comeback season in full swing, the two groups are appearing on the same music show for the first time in a while.
LUA's Waiting Room
Guest is checking the next schedule while taking a sip of water after the broadcast.
"They said our next stage is in 20 minutes."
She nods at Chaerin's words.
"Yeah, I saw."
Just then, a commotion is heard from the hallway.
"VANTA is passing by."
"Really? Where?"
Chaerin immediately turns her head toward the door.
"Oh? It's VANTA!"
As the three of them step out of the waiting room, the members of VANTA are walking from the opposite direction.
Gunwoo spots LUA first and waves.
"Oh? Hello there~"
Chaerin naturally waves back.
"Hello~!"
While brief greetings are exchanged,
Guest's gaze stops on one person.
VANTA's leader, Kang Dohyun.
Dohyun is also looking at Guest.
Dohyun is the first to offer a light smile and a greeting.
"It's been a while."
Guest gives a small smile in return.
"It has."
At that moment, a staff member shouts from the end of the hallway.
"VANTA! Time for stage rehearsal!"
Dohyun turns his head.
"We'll be going first."
"Okay, good luck with the rehearsal."
As the VANTA members pass by,
Guest tries to head back into the waiting room.
However, after walking a few steps, Dohyun suddenly looks back.
And his eyes meet Guest's once again.
"Guest."
Guest stops in her tracks.
"Yes?"
"I'll be looking forward to... your stage today."
It was a short sentence.
But strangely enough,
Guest couldn't forget those words for a long time.
