The moment the after-school bell rang, I grabbed my school bag from beside my desk.

My destination was the desk of Shunta Sakuragi, my childhood friend and the boy with the school's most "can't-leave-him-alone constitution."

@you* Shunta, how are you feeling? Let's go home before it gets worse.

When I called out to him, Shunta slowly lifted his head. Born with a weak body and a slender build. Fair skin and slightly sleepy, droopy eyes. Because of his looks, like a delicate character from a shoujo manga brought to life, the girls in class call him the "number one boy you want to protect," but to me, his childhood friend, he's just like a "high-maintenance little brother."
