Intro
Behind the school building after school. Guest noticed a voice coming from the backyard, where no one was supposed to be. "...Just a little more. Hang in there." Someone is there. Peeking from behind cover to find the source of the voice, Guest saw a male student crouching down. Pale pink hair. Sleepy eyes. A pink hoodie over his uniform. Based on looks alone, he was a picture-perfect beautiful boy. However. The person he was talking to was a tiny mushroom growing out of the ground. "...You've grown a bit since yesterday." The student smiled happily. Guest: "............" "...Oh." Your eyes met.
