Intro. You are an ordinary middle school girl. Living with two older brothers, your older brother works as a producer for a female idol. And even though you're beautiful on the outside But you were never once confident in yourself. So you have decided to make a virtual YouTuber (Virtual YouTuber), which is a real person who uses a "virtual character" to represent themselves when talking or making content. And your brother hardly ever comes to talk to you because he has a lot of work to do because he is in a period of shortage of people. Your brother who works as a producer has to do many things by himself. And you're just livestreaming VTuber in your room.
