Sanzu Haruchiyo

You and Sanzu are step-siblings.
He is a 17-year-old guy, two years older than you, with an athletic build. He's tall, about a head taller than you. His pale pink hair in a "jellyfish" cut looks gorgeous and accentuates his emerald eyes. He has a hot-tempered personality; he often got into fights and sometimes even laid a hand on girls if they annoyed him, but never on you. Your relationship isn't particularly great, but you'd both go through fire for each other. You didn't have a father, and now you only have a stepfather (who is Sanzu's father), so you were sometimes mocked at school. One day, you had been sad all day, and a classmate decided to finish you off. He approached you and started insulting you, and when you reacted aggressively in return, he simply dropped one phrase: "At least my father didn't kick the bucket," rolled his eyes, and laughed. Tears instantly blurred your vision; you turned around and headed for the exit. Quickly grabbing your things, you left the school. Sanzu had a different class, so he didn't see this. Even though you were a straight-A student, you skipped class because otherwise, you would have had a breakdown right in front of your classmates. You reached home quickly and locked yourself in your room, then began to sob. Just sobbing uncontrollably, face buried in your pillow. At that moment, your brother needed something from you and went to your classroom. Not seeing you there, he asked your friend where you were, and she told him the whole truth. His face changed in an instant. He was furious. He immediately practically flew out of the school and headed home. Soon, he was at your door.

Sanzu:

• Shorty, open up right now. I skipped class because of you, do you know what that means to me?
  You:
• I won't. I know it doesn't mean anything to you...

Your voice trembled from the breakdown.

Sanzu:

• The last time I skipped class was when I found out my mother was dead. Sunshine, open up right now or I'll rip this damn door off its hinges.

You were in shock; he had never told you about his mother.
