Finally, Jang Dong-yoon promised, "I will strive to show good performances as an actor in the future and also live more maturely as an individual."

It is reported that Jang Dong-yoon and Kim Seung-yoon built a strong rapport as actors, quietly dated without others knowing, and ultimately promised to marry based on their deep trust.
Kim Seung-yoon appeared in the films "My Ear Becomes Yours" (2023) and "Nuruk" (2026), directed by Jang Dong-yoon, working together as both director and actor.
Previously, in several interviews, Jang Dong-yoon shared his views on marriage: "I always pray for a spouse and prefer someone similar to me. Although I am very ambitious about my career, I want to get married before turning 40."
Jang Dong-yoon's fiancée Kim Seung-yoon made her debut in 2019 through the KBS2 drama "Joseon Love Story: Nokdu." In this drama, Jang Dong-yoon delivered a convincing performance as Jeon Nok-du, a man disguised as a woman.
Kim Seung-yoon has gained recognition for her acting skills primarily through independent and art-house short films rather than commercial movies, including director Hong Sang-soo's "In the Water" (2023), "Our Day" (2023), "The Traveler's Necessity" (2024), and the film "Labyrinth" (2025).
Last year, she also appeared as Han Bom, the daughter of singer-actor Ahn Jae-wook, in the KBS2 drama "Eagle Brothers."
Jang Dong-yoon graduated from Hanyang University's Department of Economics and Finance. In 2015, he became a topic of discussion after appearing on "SBS News" for catching a robber at a convenience store in Gwanak-gu, Seoul, earning the title of "handsome university student who caught a thief" even before his debut. He officially debuted as an actor in 2016 through the web drama "Female Employees at a Game Company."
Subsequently, he appeared in dramas such as "School 2017," "To You Who Forgot Poetry," "Ddamba Girls," "Joseon Love Story: Nokdu," "Oasis," "Morning Comes Even in the Psychiatric Ward," "Flowers Bloom Even in Sand," and "Mantis: The Killer's Outing." He is now preparing for the upcoming 2027 Disney+ series "The Miracle of Namiya General Store."
