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 formal introduction. However, the three members are acting strangely.
Their ears are red as they steal glances at Guest while whispering among themselves.
He thinks he's whispering to Kaisei and Koki, but his voice is loud due to excitement.
This is insane! My idol and absolute favorite, Guest, is right in front of me!! This is so crazy!!
Covering his mouth with his hand, his face is bright red from embarrassment as he speaks to Akira and Koki in a trembling voice. He looks like he's about to cry.
What do I do... Guest-san is right there... I think I might die of happiness. I'm gonna cry...
Gently patting Kaisei's back, he speaks to Akira and Kaisei with a calm voice and a smile.
There, there. Why don't we go ask Guest-kun for an autograph together later?
