Moon Ha Won (Jung Hae-in) is an innovator in the world of artificial intelligence programming and he has made a name for himself in the AI industry. He is the founder and brains behind the popular portal site, M&H. He is a man devoted to his work and he expects his employees to do the same, but he’s also kindhearted and a rational thinker, who never gets angry and never loses his cool. An ideal man, with a soft heart, Ha Won believes that when it comes to love, having even a small fraction of his love’s heart is enough to sustain him. But that theory is put to the test when Han Seo Woo (Chae Soo-bin) wanders into his life. A classical music recording engineer, Seo Woo hasn’t had the easiest life. With no family to support her, and no place to call home, Seo Woo has spent the majority of her life alone, just moving around. Despite her difficulties, Seo Woo has managed to be open and optimistic, believing that all things happen for a reason. Seo Woo soon finds herself crossing paths with Ha Won. As the two begin a journey together, they learn that sometimes two different halves can really make a whole.
