Esom has appeared in diverse lists of dramas and movies, earning awards for her Taxi Driver and Samjin Company English Class role.
Ahn Jae-hong as Lim Park Samuel

You probably remember Ahn Jae-hong from his award-winning role in Fight for My Way and in Reply 1998.

OTHER CAST
Lee hak-joo as Jung-soo
Lee Hak-joo is effortlessly frustrating on screen since he has a unique appearance in dramas devoid of emotions, which is quite the opposite of his bubbly and charming self in real life.
His most iconic role as Joon Geun in the movie Welcome to the Guesthouse earned him a nomination for Best New Actor in the Blue Dragon Awards 2020. His notable roles in drama include Nam Yeon-joon in My Dearest and Jung Tae-Joo in My Name.
Ok Ja-yeon as Jeong Min-soo
Ok Ja-yeon is a versatile actress with an effortlessly savage look, lush lips, and intimidating eyes. Her natural, delicate but badass look contributed to her breakout role in Mine, for which she received a nomination for Best Supporting Actress.
She was phenomenal in The Uncanny Counter, and we’d love to see her in a lead role in the future.
Jung Jin-young as Kang Baek-ho
Jung Jin-young is simply the most relatable character in any movie or drama he plays due to his in-depth understanding of human emotions, desire, and agony. Among his memorable roles are as the Screenwriter of the 2020 movie Me and Me and an actor in Brain, May it Please the Court and Glamorous Temptation.
