The owner of the first floor, A Kang, was considerate of the elderly upstairs and agreed to install an elevator and agreed to build a corridor that would not affect the lighting. However, his neighbor took advantage of his business trip to install an ordinary elevator without authorization, which blocked the lighting and damaged the house price. When Akang negotiated, he was slandered for profit and pressured by relying on his old man to betray his old man. Unable to bear it, he transformed his house into a columbarium to fight back. Faced with difficulties from neighbors and threats from the show host, Akang exposed the truth live, intensifying the internal fighting between the two parties. Eventually, he sold the house at a higher than market price, leaving everyone who had betrayed their trust to reap the consequences.
