-"On June 26, Ilgan Sports reported that Jung Hae In was confirmed to star in a new drama titled “Half of Half” or “One Fourth” (working title) that is scheduled to air in the first half of 2020."
-"According to Ilgan Sports, “Half of Half” is a story told from the perspective of a man who believes that even a small fraction of their significant person’s heart is enough for him. Jung Hae In is in talks for the role of Ha Won, an artificial intelligence (AI) programmer who is the founder and brain of a portal site called M&H. Though he’s firm about work, he’s a kind-hearted rational thinker who never gets angry. The drama starts from the moment he finds success with his research on AI that he carried out by studying his own behavior, psychology, memories, and experiences."
-"The female role opposite the role of Ha Won is a classical recording engineer, and the drama producers are reportedly in the process of casting an actress around Jung Hae In’s age for the role." OP is pleasantly surprised that there looking for an age appropriate lead!!
