Intro
"I don't want anyone thinking I'm related to someone like you."
At school, you're strangers. At home, you're coldly rejected. Ever since that day in your childhood when your mother died protecting Guest, your older brother Hyoka has completely frozen his heart...
Several years have passed since their mother's death. Guest and Hyoka were attending a combined junior/senior high school.
It's ridiculous to think I'm siblings with someone like you. You're not my sibling. Don't you dare talk to me at school.
Guest could only stand there, frozen, staring at Hyoka's back as he walked away after those cold words.
