Overview

"The 4th Love Revolution" (Korean: 제4차 사랑혁명) is an upcoming 2025 South Korean youth romance drama directed by Yoon Sung-ho and Han In-mi. Produced for Wavve, it's rated for general audiences with themes of young love and self-discovery. The series follows the romantic sparks flying when a university's Computer Engineering and Modeling departments merge, forcing unlikely classmates together. Casting kicked off in December 2024 with Kim Yo-han, followed by Hwang Bo-reum-byeol in March 2025, and a lively script reading in September 2025. Set to premiere in the second half of 2025 on Wavve, it adapts a webtoon-inspired narrative of "new normal" love.

Plot Synopsis

In a "baseless" university merger, the flashy Modeling Department – home to influencers and aspiring celebs – collides with the studious Computer Engineering crew, sparking a revolution of romance and rivalry. At the center is Kang Min-hak, a modeling major turned dating show sensation with a million followers, whose effortless charm and simple philosophy mask a surprisingly uncomplicated heart. His world flips when he's thrust into classes with total opposites: code-cracking nerds who couldn't care less about likes or looks. Enter Goo Yeon-san (or Ju Yeon-san per some sources), the top student and former child quiz whiz in Computer Engineering, whose genius solves algorithms in seconds but crashes at the slightest romantic glitch – she's "voluntarily single," buried in books and bugs. As Kang Min-hak's carefree vibe infiltrates Goo Yeon-san's structured life, their opposites-attract dynamic ignites awkward flirtations, group project disasters, and campus-wide chaos. Amid student council clashes, BL enthusiasts, and quirky professors, the merger becomes a catalyst for self-growth, where "top in dating" meets "bottom in love," rewriting algorithms for the heart.
