If you share the nipslip photo with Paul after losing the bet (so on the early stages of the sharing path), he tells you it's Merry. If you don't, he straight out lies:
Code:
p_nvl "Wait... she’s coming out."
f_nvl "So? Did you talk to her?"
p_nvl "I tried."
p_nvl "But she said she was in a hurry."
p_nvl "Didn’t even tell me her name."
And then later, seeing the photo on the laptop that is recognisable as Merry:
Code:
"That photo from the changing room—it wasn’t some random girl, it was my fiancée!"
"Now it makes sense why Paul dropped the subject so quickly."
"Though it’s kinda weird he didn’t say anything to me about it. Hmmm..."
(Sidenote: It's a damn sight easier to look for stuff in this game than in Stay Online!
