Naoko (29), who wants her life to go according to her perfect plan, has graduated from a famous university, has been promoted steadily, and is active enough to be interviewed by an online news outlet. Naoko is a perfect person in her studies and work, but she is very impatient inside, as she is finding it difficult to achieve only her plan of "getting married at age 30." In fact, Naoko, who had never been in a relationship before, registered for a "matching app" that was recommended to her by a straw on the eve of her 30th birthday, and for the first time in her life, she became "popular."
