하이드 지킬, 나
A chaebol executive with a split personality spars with a circus leader determined to save her troupe, which he’s trying to eject from his theme park.
Ha-na, a leader of a circus, pleads to Goo Seo-jin, the director of Wonderland, not to disband the crew.
Upon discovering he saved Ha-na, Seo-jin thinks Robin has returned. Meanwhile, Ha-na gets short-term amnesia.
Ha-na is confused by Seo-jin, who looks just like Robin. Meanwhile, Robin realizes Ha-na brought him out.
Seo-jin terminates the contract with Ha-na, afraid she will make Robin return. Ha-na demands to know why.
After a fight, Seo-jin and Robin compromise to stay as Robin at night and Seo-jin during the day.
Ha-na confesses her feelings, leaving Seo-jin in shock. Upon hearing she's in danger, Seo-jin looks for her.
Seo-jin's dad tells Seo-jin to end the circus contract since Robin and Ha-na are in love, but Seo-jin says no.
Seo-jin falls ill and blames Ha-na for making him suffer from anxiety. Meanwhile, Robin offers Seo-jin help.
Ha-na thinks Seo-jin is Robin's twin. Mr. Min gets worried and advises Robin to tell her the truth.
Chairman Goo, Seo-jin's dad, tries to send Seo-jin abroad. Meanwhile, Tae-joo threatens to kill Dr. Kang.
Seo-jin shows Ha-na that Robin is his other self and says they have a condition called DID.
Tae-joo watches Seo-jin's video. Also, Seo-jin tells Ha-na he will take loving Robin to mean loving him too.
Robin tells Seo-jin to suspect those around him. Tae-joo is flustered as he sees Seo-jin sharing his memory.
Seo-jin tells Tae-joo that his dad helped the kidnapper, but he distrusts him. Meanwhile, Ha-na falls ill.
Tae-joo says Seo-jin lied about his father to survive, but Seo-jin says he'll bet everything that it's true.
Robin asks Ha-na to build a new workshop together. Meanwhile, Seo-jin comes to the circus crew's office.
Ha-na gets trapped by reporters at Robin's. Seo-jin tries to tell them he has a DID, but Ha-na stops him.
Seo-jin thanks Ha-na for allowing Robin to exist, and news articles about him and Robin help Wonderland.
