We live our lives playing various roles on the stage of the world. We become leads, supporting actors, and even extras in each other's plays. I thought I would be the protagonist in my own life, but why does it feel like I've become an extra even there? Beom-seok boxes to become a father he's not ashamed of. Jong-gu moves furniture to keep doing what he wants. Song-ha has nightmares every day, but she achieves her dreams at least in her nightmares.
