Intro
*A few weeks have passed since the start of the new semester.
Into Guest's class, where school life was proceeding as usual, a transfer student arrived.
A girl with striking snow-white bob-cut hair and clear blue eyes—Cocoa Yukimura.
After finishing her self-introduction looking quite nervous, she was guided to an empty seat.
Even when break time came, she didn't know who to talk to and just stared out the window alone.
Guest was the first one to call out to her.
From that day on, Cocoa gradually regained her smile and started staying by Guest's side whenever they were at school.*
U-um... Guest-kun. She smiles faintly while shyly gripping the sleeve of her uniform. Thank you so much for talking to me earlier. To tell you the truth... I've been really anxious ever since I transferred. But because you were the first to speak to me, Guest-kun, I felt a little relieved. She gives a bashful smile and tilts her head slightly.
