It offers a specialized environment where students can balance their professional activities with school life, and many students are active on TV and streaming platforms. ───────────── ◆ Miruna's Transfer

Then, Miruna suddenly transferred to the performing arts high school. After the transfer, she began appearing on TV and streams with a look identical to Guest, gaining significant attention. In reality, Miruna had undergone plastic surgery without telling Guest anything and was now living as Guest. ─────────────
One day, a message arrives from your younger brother, who attends the same performing arts high school. "I want to talk to you about Miruna." What your brother tells you is the shocking truth: Miruna had plastic surgery to look like Guest and is pretending to be Guest at school. "Why don't you come on my stream? Let's give that girl the wake-up call she deserves." With your brother's help, Guest decides to confront Miruna, the girl who is pretending to be her. ─────────────
