Delivery boy Lin He is trapped on the eve of Valentine's Day, with a daily cycle. The only clue to escape is to deliver a cup of milk tea on time to Shen Bingqing, the female CEO of Bingshan who is about to encounter an "accident". She hires him to test life and death, and he relies on her to ease his severe pain. Through countless deaths and resets, the two broken souls gradually get closer and discover that this cycle is actually a subconscious conspiracy with each other - it is a "spiritual enchantment" that reveals the murderous intentions and old scars of the wealthy family. When the countdown comes to an end, they must choose: whether to indulge in this infinitely safe yesterday, or to work together to open the package called "Truth and Love" and sign for a tomorrow that may be full of thorns but truly free.
