Lee Sang Yi to play a detective in new thriller 'Married Woman Killer'

Recently, Kim Mu Yeol and Lee Sung Min, the lead actors of the new series Teach You a Lesson, made an appearance on Netflix Korea.
When asked, "What have you been up to lately?" Kim Mu Yeol replied, "I've been doing well these days. I'm [taking a break from] work and just resting, and I've been taking care of my son."
Yoo Byung Jae then asked, "We don't have any experience with it, so between parenting and work, which is more difficult?"
Kim Mu Yeol unhesitatingly replied, "Childcare is physically more demanding." When asked, "Is childcare harder than fighting Ma Dong Seok?" Kim Mu Yeol answered, "Of course! [Fighting] Dong Seok hyung can't even compare."

Previously, Kim Mu Yeol starred opposite Ma Dong Seok in films such as The Roundup: Punishment (2024) and The Gangster, the Cop and the Devil (2019).
Kim Mu Yeol married Yoon Seung Ah in 2015 and welcomed their son in 2023.

He also stated, "While parenting is physically exhausting, it also makes me very happy. Through raising my child, I've come to realize just how precious and special another human being can be to me. I've been feeling that a lot lately while parenting."
Teach You a Lesson revolves around the Educational Rights Protection Bureau (ERPB), established to save South Korea's crumbling school system and restore teachers' authority, which has been undermined by unruly students and overbearing parents.
In the series, Kim Mu Yeol plays Na Hwa Jin, an inspector from the Educational Rights Protection Bureau who tackles school problems his own way. Lee Sung Min portrays Choi Kang Seok, the Minister of Education who founded the bureau.
Teach You a Lesson is streaming on Netflix.
