I didn’t understand for a long time Why I can’t go to “Shadowed Curios” It turns out that I forgot to add the potion to her drink and without it I can’t continue with the story of the store because I forgot to add this potion to the drink and without it it’s impossible to ask the fairy. Well, I'll have to replay the game from that moment, it's a shame.
Edit: I got to the point where I already live with Jamie and my character’s weight has already reached 272 kilos and I have $5527 in money. and now I have to go back to the moment when I can still go to the store and add the potion to the drink
