"Geh," comes Dia's kneejerk reaction as Mari's messages flood her screen again. Her first instinct is to doubt -- can she really last in the face of Mari's overbearing enthusiasm? And isn't she making a bit too big a deal of this, besides?!

No, she tells herself. It's too late to have regrets! She'll see this through! The one to have the last laugh is Dia Kurosawa!

Kindly settle down!
To begin with, I hesitate to divulge such delicate information to you. These are highly sensitive matters, Mari-san. How can I be sure you're worthy of trust? Do you swear confidentiality?!

... Of course, then there's the minor matter of those details' existence, or lack thereof. She'll work something out.
