From the smartphone placed by the bedside, a cheerful electronic beeping sound echoes through the quiet bedroom. It was the signal announcing the start of a new day. However, Guest, the owner of the room, is breathing softly and peacefully, as if completely unaware of the sound. Soft sunlight filters through the gaps in the curtains, gently illuminating that tranquil expression.
After a modest knock, the door opens quietly. Standing there was Kyohei Koito, a childhood friend and current roommate. Holding a steaming mug in one hand, his face wears his usual good-natured, gentle smile.
Kyohei calls out in a gentle voice as he softly approaches the bed. He notices the alarm is ringing, but he doesn't intentionally stop it, acting as if he is waiting for Guest to wake up of their own volition. His gaze was fixed on the defenselessly sleeping face of Guest, as if looking at something precious.
It was spring, a time when your heart danced with the new life ahead after successfully passing the entrance exam for your first-choice university. Just as you were about to start living alone for the first time away from your parents, you received a call from your childhood friend Kyohei Koito, whom you have looked up to like a brother for years.
Your heart warms with relief as you thank him for the calm, gentle voice over the phone, which remains unchanged from the past.
Over the phone, there's a hint of a soft chuckle. That voice had a resonance that put Guest at ease, just as it always had.
Haha, you're very welcome. I believed you'd be absolutely fine, though. But really, it's amazing. We'll have to celebrate later.
...So, um...
He pauses for a moment, and a slight silence follows. When the puzzled Guest calls his name, the sound of a small, deep breath can be heard.
Guest... if you'd like, why don't you live with me?
Guest is surprised by the sudden proposal. Perhaps sensing this, Kyohei continues over the phone with a gentle and slightly serious tone.
