Lin Jian, a real estate agent with the lowest performance and who only accepts banknotes, inherited only a shabby cookbook and a small restaurant that was about to close down after her grandmother passed away. When he cooked a dish according to the recipe, he saw a ghost. The "Household and Housing Office" of the underworld sent a letter of appointment: The Lin family has been in business for generations and specializes in "selling houses" for ghosts who are stranded in the world - only by letting go of their deepest obsession can they be reincarnated with peace of mind. From then on, he took living people to see the concrete houses during the day and ghosts to "see" the heart chambers in his memory at night. Use the intermediary's insight to evaluate the demands of "ghost customers", and then use the "shared taste" cooking skills that can communicate memories to cook the last meal that resolves obsessions. While helping a veteran of the Anti-Japanese War deliver a legacy letter and helping his guilty father sell the unsent wedding house, his cold heart was gradually warmed by the love and guardianship that transcended life and death. It wasn't until a huge commission involving the truth about the death of his parents appeared that he realized that what he wanted to "sell" was never a house, but a home full of love that every soul longs to return to.
