Yong-ki hides behind a facade of optimism even as he turns down boring job offers in the hopes that his comedic talent will be noticed on a famous talent show he's auditioning for. Meanwhile, Jung-yun has to support them both as well as bear the pain of a miscarriage that Yong-ki is trying his best to forget. To make matters worse, Jung-yun discovers that she's dying from cancer and though Yong-ki suspects that something is wrong, she never tells him about her illness.
