The 4th Love Revolution: A bold youth romance starring Kim Yo-han and Hwang Bo-reum-byeol
Directed by Yoon Sung-ho and Han In-mi, with a script penned by Creative Group Songpyeon, The 4th Love Revolution is produced by Story Mob and Binzy Works. The story unfolds when a sudden university merger combines the Computer Engineering and Modeling departments, bringing together students from completely different worlds.
At the center of this change is Kang Min-hak (Kim Yo-han), a top influencer and rising model, and Joo Yeon-san (Hwang Bo-reum-byeol), an academically gifted student with little experience in dating. Their contrasting personalities and approaches to life set the stage for a unique romance filled with humor and heart.
Kim Yo-han takes on the role of Kang Min-hak, a charismatic modeling student who skyrockets to fame after appearing on a reality dating show. With a million followers and undeniable charm, he turns heads wherever he goes.
However, beneath his polished exterior, he has a surprisingly simple and carefree mindset. His life takes an unexpected turn when he crosses paths with Joo Yeon-san, an engineering student whose world revolves around logic and academics rather than relationships.
Hwang Bo-reum-byeol plays ace of the Computer Engineering department, Joo Yeon-san, who is a young quiz prodigy. She excels in the classroom but is completely inexperienced when it comes to love.
As she navigates this unanticipated college shift, her interactions with Kang Min-hak challenge her in ways she never imagined, leading to moments of comedic misunderstandings and heartfelt growth.
With its vibrant premise, dynamic leads, and a mix of romance and humor, The 4th Love Revolution is reported by OSEN to be an exciting journey through love, self-discovery, and the unpredictable twists of college life.
As per Soompi, Hwang Bo-reum-byeol expressed her enthusiasm for both the role and reuniting with her School 2021 co-star Kim Yo-han.
"When I first read the script, I was intrigued by the emotional comic elements that I usually like. I'm also thrilled to work with Kim Yo-han again— He’s such a cheerful friend, so I think we’ll be able to film happily in a good atmosphere," she shared.
Kim Yo-han also shared his excitement about The 4th Love Revolution, saying,
"The title 'The 4th Love Revolution' was refreshing. I laughed a lot and was excited when I read the script. Also, the character 'Kang Min-hak' was fun and impressive, so I really wanted to act it. I am looking forward to showing you a new side of me."
Kim Yo-han (김요한), aka Yohan (요한), is a South Korean singer and actor and also a member of the boy group WEi and previously debuted with X1 after ranking first on Produce X 101. He began his solo music career with the digital single No More on August 25, 2020, and made his acting debut in A Love So Beautiful (2022-2021).
Hwang Bo-reum-byeol made her acting debut in the 2020 Naver TV web series The World of My 17. Beyond her role in School 2021, she has appeared in Dear.M (2022), Maestra: Strings of Truth (2023), and The Secret Romantic Guesthouse (2023–2024).
