Park Sung-woo

Woo-jin is Korea's top star - every item he wears and uses are always a hot potato and gets sold out overnight. He is especially famous for remembering all his fan names. He seems to be just perfect, but there is one big secret that nobody knows - he cannot forget but only remember things. Woo-jin is forced to relive painful moments over and over again, feeling the same amount of anguish each time. One day, Woo-jin encounters a woman named Hae-soo, who suffers from the opposite pain from him: her memory resets every 30 days.

So-eun is a high-school girl living in the countryside. She’s skinny and quite bad at basketball, but she really likes basketball. The problem is that her school doesn’t have enough players for a team, and they’re trying to dismiss the basketball team. So-eun doesn’t have anybody to share her frustration. Then one day, Yu-jin, a washed up movie actress, and Yong-sik, Yu-jin’s fan who also goes to the same school as So-eun, appear in So-eun’s life. Now, So-eun’s time starts to run quite differently from before.

Under the overall theme of unrequited love and having a crush on someone unattainable, the drama tells stories of various happenings that can arise in such relationships. The stories are told in perspectives from both man and woman, as if it were written from an omniscient point-of-view, which allows viewers to sympathize with both sides and adds another layer to seemingly ordinary incidents between men and women.
