Comments of chapter undefined of The First Store System

Wasn't the eye the cosmic contract beast or something? Why did it suddenly become a Deva

It makes no sense that Mc sent his first customer, the first being he saw after Awakening away that fast. I would makes more sense if Mc was unwillig to to send her away that fast becouse he likes to Chat more with another being (except the System) but the System then warns him and Mc then send her away a little unwillig. Afterall it was said that Mc's personality is still a little child like so this would fit more.

how did the elf see or find the store???

so the explanation is bit a lie, the eye either demon or devas or else depends on what customer believe
