In an age where love and marriage are 'calculated' and you don't want to lose, a fresh love comes to two men and women living in the smoke of modern society. Hyun Da-Young, a 35-year-old career woman who has followed the elite course but is anxious because marriage is not going as planned. Choi Woo-Jin, a 35-year-old single man who thinks his older sister's failed marriage is due to their age difference. Will they, who are past the ideal age for marriage and are impatient, be able to overcome the 10-year age difference under the pressure of reality and become pure in the face of provocative love?(Source: Kakaopage, translated)
