Dinesh "Dino" Srivastav is a socially awkward, trivia-obsessed nerd secretly in love with his beautiful colleague, Meera. During a company offsite in Japan, a heartbroken Dino makes a wish at a Fortune Bell to be with her for just one day—not realizing how chaotically it will be granted. After a shocking revelation of her CEO boyfriend, Meera suffers an accident and wakes up with Transient Global Amnesia (TGA). She has lost her recent memories, but only for the next 24 hours. Mistaken for her boyfriend by a doctor, Dino lies to protect her emotional state, leading the two on a magical, whirlwind journey through the Sapporo Snow Festival.
