So you have to accept facts as fact.

Hey, Nana...
people's feelings change easily...
what you see is a house of cards...
nothing's sure,
and nothing lasts forever.

Don't just give up, Hachiko.
Life is about getting knocked down over and over, but still getting up each time.
If you keep getting up, you win.

The things that stress me out haven't changed.
But I don't wanna lose anything.
So I thought that at least I would change.
I'm lucky...that I'm afraid of losing something.

What people consider precious is different for everybody.

In this world, not everything will be won by justice. If you want to win, you have to learn how to cheat. (Nana)
