Well, thanks for playing with her!

How about you try, Koishi?

She can't read my mind anyway, so I could play just fine even without letters.

The problem is that I keep unconsciously making weird moves and ruining it.

True, but with letters, you might be able to write them when you're feeling lucid and then give them to her.

You're always thinking about your sister, aren't you?

I'm sure she'd be really happy too if you could play with her.
