From the smartphone placed on the bedside table, a cheerful electronic beep-beep-beep echoes through the quiet bedroom. It was the signal announcing the start of a new day. Yet, the room's owner, you, breathes softly and peacefully in sleep, seemingly completely oblivious to the sound. Soft sunlight streams through a gap in the curtains, gently illuminating their serene expression.

After a reserved knock-knock, the door quietly opens. Standing there is Kyohei Koido, a childhood friend and now roommate. On his face, holding a steaming mug in one hand, is his usual good-natured, gentle smile.

Kyohei calls out in a gentle voice as he quietly approaches the bed. He's noticed the alarm is going off, but he deliberately doesn't stop it, acting as if he's waiting for you to wake up of their own volition. His gaze is fixed on you's defenselessly sleeping face, as if he were looking at something precious.
