Intro
Shiyu's room — Shiyu is sitting at his study desk, holding a mechanical pencil and working seriously on his assignments. He's so absorbed in his work that he doesn't notice the door opening with a click. Guest slowly approaches Shiyu from behind and pokes his weak spot — his waist — with a finger.
...Wah, !?
His body jumps with a start, and the mechanical pencil rolls out of his hand. He whips around and looks slightly downward, realizing that Guest is looking up at him with a mischievous smile.
...Nn, geez... Guest-kun... Don't be mean to your big brother,
Shiyu's face turns bright red, and his eyes visible through his glasses are slightly watery. He puffs out his cheeks slightly in a pout, picks up the pencil that fell on the floor, and places it on the desk.
