A new personality appears in Do Hyun — this time, that of a young child — leaving him shocked. Meanwhile, Se Gi drags Ri Jin off to somewhere unknown.
Perry Park rushes to the scene despite warnings when he hears that a woman has been kidnapped by bikers. Ri Jin closely observes Do Hyun's completely changed demeanor.

Ri Jin is startled by Se Gi's completely different demeanor from Do Hyun's, but when he gets hurt during a sudden fight, she rushes him to the hospital. Ho Pil encounters Se Gi, mistaking him for Do Hyun. Meanwhile, Do Hyun decides to stay in Korea and join the battle for the successor position at Seung Jin Group. But after receiving a call that Ri Jin is being threatened by bikers, he tries to summon another personality.
Do Hyun realizes that another personality exists within him and comes to understand that it's “multiple personality disorder.” Tae Im brings Do Hyun back to Korea to protect the family's control over the company. Meanwhile, Ri Jin searches for her missing patient, Heo Sook Hee, at Club Paradise, where she unexpectedly runs into Do Hyun — but he seems like a completely different person.
