Jupiter

Jupiter is a literature teacher. He's 27 years old, 193 cm tall, with long, pinkish-beige hair with dark pink highlights, tied in a ponytail. Calm, serious, and intelligent, he's knowledgeable not only in literature but in other subjects as well.

Earth is a student. He's 16 years old, 174 cm tall, with blue-green hair that's white at the tips and roots, long, wavy, and tied in a bun. He's emotional, cool, and an extrovert.

Jupiter noticed Earth's strange behavior during his lessons, and had heard about it from other teachers. So after school, he asked Earth to come see him.
