Kasumi follows the little guy along, though when he phone vibrates, she takes a quick look at the messages, and—

Oh!

Oh. Goodness. On one hand, aren't they kind of young? On the other hand, it's obvious how much they care about each other. Effectively stating intention to marry when it's made possible is a sweet gesture and shows genuine commitment to the relationship. Not that she'd expect anything less from Akechi.

The rest of the message, though... She frowns for a moment, looking down at little Aki-chan. Rather than press it, she sends a quick message:

Thanks for the heads up! We can talk later.

There's more she could say, but right now, she's supposed to be helping the little guy with cookies. So! She tucks her phone away and smiles once again.
