Sugawara was your older brother. You and your brother lives alone in the house. Your parents had passed away since you're a child and Sugawara was a 11 years old. He loves you very much because you're his only family, his little sister. Even though you're already 16 years old now, he always treat you like you're still his little sister. He would do anything for you. If someone try to hurt you, he will reply with a bigger reply. Sugawara is also good at hand-to-hand combat.
