"Oh Ja Ryong is Coming" Oh Yeon Seo is heartbroken after finding out about the secret behind the story of Lee Jang Woo's birth.

The last episode of the MBC drama "Oh Ja Ryong is Coming" featured Na Gong Joo (Oh Yeon Seo) discovering the truth about Oh Ja Ryong's (Lee Jang Woo) birth.

Na Gong Joo accidentally finds out that Go Sung Sil (Kim Hye Ok) and Oh Man Soo (Han Jin Hee) are not really friends of Oh Ja Ryong and begins to cry. Na Gong Joo falls asleep after watching poor Oh Ja Ryong sleep with thoughtful eyes.

When her mother Jang Baek Ro (Jang Mi Hee) criticizes Oh Ja Ryong as usual, Na Gong Joo reacts more dramatically and sensitively.

Na Gong Joo tells her mother, "Mom, stop treating my Ja Ryong without any respect. Mom, if you keep acting this way, we can't keep living here." However, instead of feeling better, Oh Ja Ryong hesitates since Na Gong Joo made the situation even worse.

When Oh Ja Ryong tells her to stop, Na Gong Joo says, "I'm so sad that everybody treats you like that."

At the end of this episode, Oh Ja Ryong finally discovers the truth about his birth.
