[does Kaito going unabashedly and happily floppy in her arms help the cheer thing]

...Good. I used to do that to Father and Miku, because I was scared and scared of hurting them. If he does it for the same reasons, it'll be better if you stay; even if he makes it hard.

Also, also, Father and I will help, too! Now that I don't have to worry about him hurting people if I do it wrong, I can help even if he doesn't ask. So he'll have you and me and Father until he can go home and sing with everyone else.
