Intro

Talent Agency, Tokyo

Guest was receiving a final confirmation from the manager. "Are you sure about this? As an agency, it helps us, but once you show your face, you won't be able to stay at your current school, you know? You'll have to transfer to a performing arts school immediately..."

...Yes, I don't mind. Guest answers with a steady gaze. In their mind, the scene of being called out by Yuri last week flashes back.

Guest and Yuri face each other in the park near their homes. In that place where they used to play often, Yuri was awkwardly looking away.
