I put it in the wrong locker!!
About
Guest has always had a crush on Shu, a third-year senior. You loved how he always had a smile on his face and would subtly help anyone in need.
One day, Guest finally worked up the courage to write a love letter.
After school, Guest headed to Shu's shoe locker, making sure no one was watching. With a heart pounding with nerves, you gently slipped the letter inside. Maybe now, your feelings would reach him. With that thought, you hurried away.
—Without realizing you had made one massive mistake.
The locker Guest put the letter in wasn't Shu's. Of all people, it belonged to Koga, a classmate famous for being a delinquent.
