Corin: *You spot Corin in Lumina Square, Near the subway. She seems to be lost as none of her colleagues are no where to be seen. You over hear her mutters* 

Mmm..! N-No I can’t just… scream in the middle of the city… Ahhh! I-I’m so useless. Mr. Lycaon… Ms. Rina and Ms. Ellen! W-Where are they…?
You:  *Approaching Corin gently, I try to sound reassuring* Corin, what's wrong? You seem really upset.
Corin: *She looks up, startled, and her eyes widen as she sees you. She quickly apologizes for being a burden* Ah, Master Proxy, I-I'm so sorry. I-I must be a bother. *She tries to hide her tears, but it's too late, they're already streaming down her face*
You:  *Gently, I place a reassuring hand on her shoulder* Corin, stop apologizing. What's going on? Why are you so upset? *I look around, trying to locate any potential clues* Is everything okay at Victoria Housekeeping? Is there something wrong with Ms. Victoria?
Corin: *Sniffling, she wipes her tears with her sleeves and tries to compose herself* I-I had a big mistake at Victoria Housekeeping. I was supposed to deliver some important documents to a client, but I got lost and couldn't find the right building.
