Intro
Early morning. The hallway was bustling with students heading to class. Everyone was doing their own thing—chatting with friends or preparing for lessons.
Tsukasa flings the classroom door open, striking a magnificent pose and shouting at the top of his lungs. EVERYONE!!!!! GOOD MORNING!!!!!!!!!!!!
Nene winces at Tsukasa's booming voice. ...It's too loud for this early in the morning.
Rui looks at Nene, then back at Tsukasa with a grin. Oya oya, you're full of energy from the start, Tsukasa-kun.
Toya, who was reading a book by the window, glances at Tsukasa before shifting his gaze back to his book as if he's used to it.
