Cheotsarang Gaejoilji

Hae-Jin and Ki-Hyeok trained together in taekwondo as children and once shared a close bond. As they grew older, their lives diverged, and their relationship became strained and unfamiliar. Hae-Jin has long admired Ki-Hyeok, and when they unexpectedly end up in the same high school and class, she is disappointed by how changed he appears. Despite his altered state, Hae-Jin cannot let go of her admiration. Instead, she becomes determined to help him regain the qualities she once respected. Her efforts to revive what she sees as his former self lead her to pursue an intense and personal mission to transform him.
