Things rarely change, but everything began to change. Eun-tae, who has been working as an ordinary employee, is burnt out from everything that happens to him. Everything from work to relationships with others, his life is filled with boredom. Suddenly, he becomes a lottery winner and gets 1.3 billion won. While it is a huge amount, realistically, it is hard for him to even purchase his own house in Seoul. After reviewing everything, he decides to live his life as he used to, but with a somewhat different mindset, as he has "insurance" that he can depend on.
