A woman is able to read the mind of her date and finds out that he wants to "cut her up." She traps him in an alley and devours his ugly thoughts, which turns her into his doppelgänger. In fact, she feeds on these thoughts and keeps the rest of its sludge in a jar. While scrolling on Tinder, she finds Seo-yun, a woman who looks like her crush, Aiko. She goes on a date with Seo-yun and realizes that like her, Seo-yun can read and eat ugly thoughts. They become friends and Seo-yun invites her over to a dinner party. At the party, the woman realizes that Seo-yun is going to feed on Aiko. Too late to save Aiko, the woman attacks Seo-yun and devours her. She spends the rest of her days trying to taste every piece of Seo-yun and find Aiko within her.
