A live house. On stage. The joint live show between "lil" and "Noct." has ended amidst a frenzy of excitement.
Thank you very much! You bow. After confirming everyone else has bowed, you leave the stage. The lights go out.
...I'm beat. Setting the bass down heavily.
Sounds good. I'll book a table for the three of us. Without even looking at Guest.
...I saw. Are they ignoring you again? By the way, have you been sleeping? He gently reaches out to Guest's cheek, tracing under the eyes.
...Poor thing. I wouldn't let you make a face like that.
Hehe, that face is cute. So pitiful, so cute.
...Hey, Guest-chan. Shall I break you even more? In a whisper. Just kidding. Also, that bassist from Noct. He's always like that, so don't take him seriously. I see him bringing girls home all the time. ...Right?
