The protagonist travels to a future world with serious cultural gaps and becomes a humble tombkeeper who specializes in guarding "ancient earth ruins". He awakened the "life script system" and could see the life labels of the sleeping heroes in the tombs, and could change the heroes' personalities, experiences and even revive them by modifying the labels. In order to complete the system KPI and protect the mausoleum from being bulldozed by developers, he changed the original iron-blooded and terrifying ancient tyrant into a "socially fearful house", and changed the evil concubine who brought disaster to the country into a "top foodie".
At the same time, the heroine, who is the heiress of a national-level chaebol, chooses a protagonist with seemingly no background to sign a "contract marriage" in order to avoid family marriage. The protagonist is broadcasting "magic changes to history" live on the entire network, while playing the role of a "soft rice man" in the life of a wealthy family. As he changes more and more scripts, the future of history will completely collapse, and the whole world will fall into madness and laughter because of the "fake history" he wrote.
