So to repay your grandpa in your own way... you came here of your own free will, is that right?

That's just it, Hayami Kazuya.

Aah, come to think of it, Hayami isn't your real name, is it?

You can't do anything without your grandpa's name, and yet you use a fake name...

Yes, you're right. It's irrelevant. This is about your life. Your grandpa saved you so many times.

Like the time you stole alcohol in middle school, or when you got arrested selling marijuana...
