Choi Yeon Woo (Yoo Jun) is a high school student and a "mono" who sees the world only in black and white, with each mono having a unique "probe" soulmate who allows them to see color. Yeon Woo's probe, Yoo Han, was once his close friend and romantic partner, but has mysteriously disappeared along with his mother. Determined to find them, Yeon Woo begins an intense search, aided by his classmate Se Hyun (Hyuk), who becomes deeply involved in his quest. As their friendship grows, Se Hyun harbors a hidden secret that could dramatically impact Yeon Woo's search. Other monos are also searching for their probes, including a female mono on her own mission, while a TV producer investigates the intriguing mono-probe phenomenon. This is a 2022 South Korean movie directed by Park Sun Jae.
