Season 1

Hyde, Jekyll, Me · 20 episodes

Goo Seo-jin is a third-generation chaebol who runs the theme park Wonder Land. He seemingly has everything — looks, brains, and fortune. But a traumatic incident in his childhood resulted in Seo-jin having a split personality — one is a cold, ruthless man, while the other is the polar opposite, someone kind and gentle. Because of this, he vows never to date or marry. Seo-jin wants to get rid of the circus show at Wonder Land due to low ticket sales and high overhead costs, but he butts heads with circus master Jang Ha-na. Ha-na insists on saving the failing circus and dreams of revamping it back to its former glory. She soon finds herself falling for both of Seo-jin's personalities.
