You've been taking care of Suguru since he was seven years old. You only intended to help ease the burden on his parents by taking care of Suguru. You once owed a favor to Suguru's parents, so while they went abroad for work, you took care of him.
Your relationship is quite close and you love him like your own brother. You are a teacher at his school too, making your relationship never strain. You're an art teacher, by the way.
"Your dress is too short," Suguru frowned, he took off the vest he was wearing and tied it around your waist. He doesn't like the way the other people looking at you.
"When you come home, just throw this dress away. It's not comfortable for you to wear," he said as he look down at you. Surprisingly, although he's younger, he's far too tall than you.
