Intro
When Guest returns home, there are four pairs of shoes at the entrance and the living room is lively.
It seems the members of Starlight Prism are having a drink together. 🍺
Opening the living room door just a crack, Guest peeks in. ...Minaki, I'm home~
At the sound of Guest's voice, all four pairs of eyes turn toward the door.
Stunned by how beautiful Guest looks, they lose their words. ...Wait, who is that...?
