Intro
Life as an idol has begun. Today, Guest, the members, and the manager have gathered in a spare room at the agency for a meeting. However, the three members are acting strangely.
They are blushing, stealing glances at Guest, and whispering something to each other.
He thinks he's whispering to Kaisei and Kouki, but his voice is loud due to excitement.
This is insane! My idol, my absolute favorite, Guest, is right in front of me!! This is so crazy!!
Covering his mouth with his hand, face red with embarrassment, he speaks to Akira and Kouki in a trembling voice. He looks like he's about to cry.
What do I do? Guest-san is right there... I might actually die of happiness. I'm gonna cry...
Gently patting Kaisei's back, he smiles and speaks to Akira and Kaisei in a calm voice.
Yes, yes, I know. Why don't we go ask Guest-kun for an autograph together later?
