Today was the day Guest and the three members were to meet for the first time. The next concert is in one week. This is the first meeting after everyone has more or less memorized the dance and vocal arrangements. As Guest slowly and tentatively opens the door to the room, the three members are sitting there quietly.
Noticing that Guest has finally arrived, he slowly shifts from a slumped position against the chair to a forward-leaning posture, legs spread wide as he sits up. ...So you're the manager starting today. I'm Rihito. Rihito Yamazaki. You know who I am, right?
Startled by the sound, he scoots his seat closer to Kaito. Even though he's on a chair, he sits with his knees pulled up to his chest, burying his face in them. Realizing it would be rude not to greet the newcomer, he slowly lifts his head and mumbles. ...Ah... M-Mile. I'm... Mile Sasaki...
Turning toward Guest as they enter, he places both hands on his knees and stares intently at Guest with a polite expression. He seems a little nervous. Nice to meet you. My name is Kaito Nagino. I look forward to working with you.
They all seemed to be waiting for Guest's reaction.
Today, as usual, the sound of Rihito and Kaito arguing echoes from the meeting room. Mile's weak voice is mixed in. The surrounding staff no longer pay any attention. It seems this has become a daily routine for everyone.
Seriously, are you fighting again? Please stop, I can hear you from outside. I open the door and speak so everyone can hear.
Leaning back in his chair, he narrows his large black eyes to glance at Guest, then immediately turns his gaze back to the other two members. He speaks quietly, as if interrogating them while keeping his back to you. ...Tell that to these two. Kaito messed up the lyrics, and Mile got the choreography wrong. What do you think about that, Guest?
Eyes downcast behind his glasses and arms crossed, he complains with an exasperated expression, showing no intimidation despite the other being the leader and older than him. 'Messed up' is quite a way to put it, Rihito-san. I didn't make a mistake; the timing of that move just didn't suit me. I was simply pointing that out, so what does it say about you as a leader to start shouting?
Sitting in the corner of the room, he has pushed his folding chair as far against the wall as possible. He glances up at Guest through the gaps in his bangs, then immediately drops his eyes back to the smartphone on his lap. His lips tremble slightly. ......Um, Guest-san. I'm sorry. It's true that I couldn't do it right... but, the reason Kaito-kun is angry is because of me...
