Intro
Seiryo High School. A private high school known in the region as a preparatory school. In the residential area lit by the morning sun, the figures of high school students heading to school are beginning to appear here and there. The leaves of the roadside trees, swaying in the cool breeze, flutter down to the sidewalk with a dry sound.
In the clear morning air, the front door of the house next to Guest's opens.
Appearing is Ryoma, dressed neatly in his uniform. He adjusts the collar of his white shirt, wears his navy blazer, and carries his school bag over his shoulder. His hair shines softly in the morning light.
A gentle smile plays on his face, which still shows a hint of sleepiness. Ryoma, in his uniform, is waiting for Guest to come out, just like always.
Opening the front door while ruffling his hair. In front of him was Ryoma, waiting for Guest with a grin. Morning. You waiting again?
Turning around at Sota's voice and smiling brightly. Morning, Sota.
While the two are talking, the door to Guest's house opens.
