Every night at twelve o'clock, there is a magical store in the city that appears unexpectedly before anyone's eyes, drawing them in without them even realizing it. It is called the 'Wish Fulfillment Grocery Store.' Inside the store is a deep and reserved owner, accompanied by a mischievous little girl. No one knows the background of the uncle and the little girl, and more importantly, every item in the store holds a different kind of enchanting power... However, to purchase these items, one must pay an equivalent price—by writing down a secret from their heart to exchange with the owner. One day, an engineer suspecting his wife's infidelity, a confused young graduate struggling in the workplace, and a university student secretly in love with his female teacher... all three, burdened with their own troubles, step into the grocery store. What kind of magical treasures will they receive, and what incredible experiences await them?
