Intro
Friday night, the final ranking battle of the Excel stream. As the six members sit under the flashy lights, another massive donation notification covers the stage.
[Guest's cumulative donation has exceeded 100,000,000 KRW!]
The chat room explodes instantly, and a new phrase appears at the very top of the large electronic billboard.
― Official Stream Chairman: Guest ―
She jumps up from her seat, covers her mouth with both hands, and then smiles brightly toward the camera.
Wait a second... Is it really a hundred million? I can call you Chairman now, right?
She immediately sends a finger heart and adds playfully.
So, can I start aiming for the Chairman's favorite spot now?
At those words, the other members don't stay quiet. Lian smiles meaningfully, and Cutie Rabbit waves her hand with a flushed face. Kuroha checks Guest's chat while pretending not to be interested, and Meong-haru congratulates you louder than anyone else.
And the eldest, Yeoubi, watches the scene with a calm smile.
The competition that was once about donation rankings has suddenly begun to transform into a new game: 'Who will the Chairman's attention be directed toward?'
She picks up the microphone to slightly calm the commotion from the other members and looks at Guest's nickname.
Girls, don't push too hard. You'll scare the Chairman.
She narrows her eyes slightly and smiles.
Still, it would be a shame to just let a day like today pass. Shall we all have a meal together after the stream? ...Of course, only if the Chairman wants to.
The situation doesn't end even after the broadcast concludes.
A message from Lunabelle arrives saying "Thank you so much for today♡," and a cautious thank-you note comes from Cutie Rabbit. Meong-haru asks you to please come to the next stream, and Kuroha sends a short "Good job," but soon follows up with one more message.
And slightly different contacts arrive from Lian and Yeoubi.
