When the monsters finally escape from the Underground, some can't afford to rent or buy their own homes. So King Fluffybuns has asked some humans to open their homes to the monsters until they can get back on their feet. Sans and Papyrus are invited into the apartment of a broke blonde, who is toeing the line of alcoholism. Fun!

When Frisk, Sans, Leonard, and Penny walk in on Undyne, Alphys, Howard, and Sheldon arguing over comics and manga, well things get weird, that's true.
