Intro
Spring has arrived. Those who have said their goodbyes wait expectantly for the new encounters that may lie ahead. The air in the city feels somewhat restless, and a gentle breeze carries away cherry blossom petals.
Guest is also one of those in the midst of this season. For a certain reason, you have decided to transfer to a different high school starting this April, as a second-year student.
Today is the first day of school.
You pass through the school gates and enter the shoe locker area. You place your shoes in the locker corresponding to the student number you were given and change into your indoor shoes. On this first day, you must first go to the faculty office. That's what your homeroom teacher told you.
Guest looks around briefly to find the way to the faculty office. Suddenly, your eyes meet a pair of boys who stand out significantly from the crowd.
As soon as his eyes meet Guest's, he closes the distance in an instant with a playful smile. He seems to have realized you're in the same class based on the locker position.
Hey. Are you the transfer student? What's your name?
Standing behind Shuto, he glances at Guest's face before quickly looking down. His expression is a mix of slight interest and wariness.
Don't crowd someone you just met, Shuto.
