49 Il (2011)

Gullible yet cheerful Shin Ji-hyun is living a perfect life: she is the only daughter of wealthy, doting parents and is surrounded by supportive best friends. She is also engaged to be married to the perfect man, Kang Min-ho, in just a few weeks. Meanwhile, Song Yi-kyung is in an existential crisis following her boyfriend's tragic death. She works third shift at a convenience store, sleeps in the afternoon, and often spends what little time she has left in the day contemplating suicide.
