Rainbow Donut

Lee In-Woo will do anything for his family - no matter the consequences. After learning about a potential plot to leak sensitive information, In-Woo travels back to Korea to track his brother’s last known location. His search leads him to Dr. Kang Do-Woon, a doctor with connections In-Woo is dying to get his hands on. But, as the two grow closer, both of them fall deeper and deeper into a tangled web of deceit and mystery that neither of them could have anticipated... Chasing this rainbow is bound to lead to something much less pleasant than a pot of gold.
