Transition to television and early success (2014–2018)
Following a temporary hiatus from acting after giving birth in 2012, Yeom worked as an assistant writer for Shim Sung-bo's film Sea Fog. She was offered a minor role in the film, which marked her return to acting. Subsequently, she continued to take small roles in films and returned to the stage for theater productions in 2015.
Yeom debuted on television with Noh Hee-kyung's drama Dear My Friends in 2016. Directed by Hong Jong-chan, the drama featured a prominent ensemble cast, including Go Hyun-jung, Kim Hye-ja, Na Moon-hee, Go Doo-shim, Park Won-sook, Youn Yuh-jung, Joo Hyun, Kim Young-ok and Shin Goo. Yeom played Soon-yeong, the adopted eldest daughter of Moon Jung-ah (played by Na Moon-hee), who was a victim of domestic violence. Yeom was praised for her role, creating an unforgettable mother-daughter bond with Na. Her casting in the drama was fortuitous. Writer Noh Hee-kyung attended Na Moon-hee's play Goodnight Mom, where Yeom played Na's character daughter, Jessi. Impressed by her performance, Noh offered her a role in the upcoming drama through Na. Yeom later recalled, "Teacher Na Moon-hee and the writer are very close, so she came to see the performance. Dear My Friends was in the planning stage, and she said that it would be nice for me to appear. The drama flourished thanks to everyone's hard work and performances. If I had met her for the first time during the drama filming, I would have frozen in front of her since she is a senior of mine I respect so much."
In the same year, Yeom acted as a supporting role in Kim Eun-sook's drama, Guardian: The Lonely and Great God. She took the role of Ji Yeon-sook, Ji Eun-tak's maternal aunt who bullied Eun-tak (Kim Go-eun) for her sister's life insurance. Although the character was a villain, Yeom's lively portrayal added comedic elements and elicited laughter from viewers, showcasing his talent as an actress.
In 2017, Yeom reunited for the second time with Noh Hee-kyung and director Hong Jong-chan for the four-episode-drama The Most Beautiful Goodbye. It was a remake of Noh's 1996 MBC drama of the same name. Yeom played Shin Yang-soon, the wife of Kim Geun-deok (Yoo Jae-myung), who was the brother of the main character In-hee (Won Mi-kyung). In 2018, Yeom worked for the third time with Noh Hee-kyung in her drama Live as Yeom Sang-soo's mother (Lee Kwang-soo). Yeom also reunited for the third time with director Hong Jong-chan in the drama Life as Kang Kyung-ah, the general manager of Sangkook University Hospital. It was written by Lee Soo-yeon.
In the same year, Yeom also reunited with Na Moon-hee in the feature film I Can Speak. She played Jin Ju-daek, a market shop owner who has a close relationship with the main character, Na Ok-bun (Na Moon-hee). Yeom was cast in I Can Speak after the casting director watched her audition video for Secret Sunshine from a decade prior.
