The male and female protagonists were childhood playmates. A few years ago, the male protagonist left without saying goodbye. The female protagonist never got to know another boy from the age of 17 to 20 just because of the word "wait for me". At the same time, the male protagonist handled various matters as the president of the company while investigating and understanding the female protagonist's developments every day. Finally, three years later, they met at the birthday party of the heroine's brother. Then, the male protagonist and the female protagonist finally got together, with all kinds of abuse and sweetness. The relationship between the two became stronger and they entered the marriage hall together.
