Charlotte

Charlotte is a major character in the game and one of the protagonist's only contacts within the game.

Introduction
Meet lonely Charlotte - an unlikely survivor who is one of the few remaining people after a deadly virus has wiped out nearly all of the human population.

Stranded and isolated from the world in her shop, Charlotte has managed to keep both Doctor Money's disease and cure at bay, never needing to leave as she had plenty to eat and drink in her shop.

Story
Earlier in the game, the protagonist will receive an ornate, pink-coloured letter, which sender is later revealed to be a woman named Charlotte. She is quite friendly, and she owns a pastry shop named "Charlotte's Delicious Pastries", located not far from his cell. She has stopped selling any pastries to anyone anymore, being fearful to get infected, but would sell to the protagonist should he come visit her sometime. Although she openly and continually expresses her loneliness to the protagonist, stating she has lately stopped contact with anyone else anymore, she tries to convince herself that there is a person left in this world besides her.

About halfway through, she pulls out a gramophone and plays french-sounding music loud enough that it can be heard by the player.

At some point in the story, she sends you a homemade cake that can be eaten, along with a curious-looking poster she found in her attic, that resembles a monochrome heart with spirals and seems to have drips coming off it. Meanwhile since she is not selling her cakes, most of her cakes has gone bad.

As the game comes to an end, Charlotte requests for the protagonist to "come down here,". She also implies that should he not come by "tomorrow evening" (Day 5, game-wise), she will kill herself. She does so later on, right before the player escapes, and writes a final letter for the protagonist to find in her pastry shop should he choose to leave his cell.

Trivia

 * Strangely. while the light of the whole city is out according to Charlotte, her pastry is still illuminated. There is also a candle besides the letter for the protagonist. A possible explanation would be the game intends to focus on the pastry and building only, and the lighting of the pastry was either supplied by more candles or an independent power source.
