[Shiho is certain that this is the way someone feels when they're playing with a cat or something. So down the grenade-slip goes. She even gives it a wiggle in his direction as if he really were an animal of some sort. (Shiho no, that's rude)]

Show-off. [Who even says something like that out loud?!]

And you know that sounds exactly like something a disillusioned adult would say. I'm not going to become the kind of adult who can't do whatever they want on their own birthday.

[He's a good person and she should stop teasing him. But he just makes it so funny and so easy? Biting her lip, she tries not to smile but mostly just fails, her own hand trembling a little.]

What do you mean "why"? Because I. Don't. Want. To. Be.

[And she's always been taught that there are limitless possibilities. She can go wherever she wants to go, be whoever she wants to be.]

Or you could just have some faith in me and believe that I'll turn out just fine.

[Minamoto did a good job, after all. If she does bad things, he'll cry.]

Thank you for this, by the way. [The grenade which she's going to carefully put away now.] I'll take good care of it.

Well, if you want to worry, I'm not going to stop you. [....because it's kind of nice sometimes to have someone care enough to worry, actually.]

...Thank you. For that too. [For trusting her. For worrying about her.]
