"Show me your true form!" Persona 5 roleplay

"I've overstayed my welcome."

(B wouldn't be apart of the party for this one)
(A) decided to spend the night with (B) the night before they get head out on a big mission with the rest of the party, one that they aren't really sure wether or not they'll come back from. But they make no mention of their fear, or the mission at all, (can be at first, if you want) and, how could they? They were a phantom thief so, they were pretty much sworn to secrecy as it was. Wether or not they spill their guts about everything, or just something completely different with a last bout of courage before the night is done, is up to you.
