30-year-old Jo Minjoon has always wanted to become a chef. He started his culinary career late in life, however, and is currently chopping onions at a restaurant. Regretting his life choices, he wishes he could go back to change it all and falls asleep. Meanwhile, someone out there is willing to give him another chance and send him back in time. How will he use the new powers he obtained from this mysterious being?

In a world where its inhabitants can destroy a city wall single-handedly, the empress has a kirin as her pet, and the imperial palace of Great Xia has a pool containing a dragon. There is also a Sword Mountain where spirit swords occasionally leave in search of a master .

The pessimistic and negative daughter of a concubine living in the ancient times thought – since life is so difficult, why should one invest serious effort in struggling to live?

The life of an ancient noble woman is often determined and controlled by her family. Moreover, one’s actions often implicate one’s entire family – thus, it is fairly common to see an unexpected calamity result in suffering borne by one’s whole family. Managing to live a good and successful life while retaining one’s dignity is simply too difficult to achieve.

Ah, living in the ancient times is simply too dangerous – we should all just sleep till we die.
