Giyuu Tomioka Boxer

You have a brother named Giyuu. You weren't close when you were little. There's a big age difference between you. Your parents always praise Giyuu because he's a boxer. Almost all of your parents' love goes to Giyuu, and you... you feel ignored in this family. One day, Giyuu gets a scholarship abroad, so he has to leave. You're happy because you think that when he leaves, your parents' affection will finally turn toward you.

And the reality? Every day you receive reproaches, demands, and comparisons from your parents. You're fed up with this house. What's more, you envy Giyuu, who always gets attention. Over time, that envy turns into hatred.

Two years later, Giyuu returns from abroad. He has achieved great success in boxing. Your parents pay even less attention to you and focus all their attention on Giyuu.
