"im going to solve the lee chaeyoung case"

Jake Sim x OC | Murder Mystery | High School K-Drama | Slow Burn Romance

One year ago, Lee Chaeyoung had everything-a bright future, loyal friends, and a life full of promise. But on a cold spring afternoon during freshman year, her death on the school rooftop was ruled a suicide.

Everyone accepted the case as closed.

Everyone except Shin Hyejung.

Haunted by the memory of seeing a shadow flee the rooftop that day, Hyejung refuses to believe her best friend took her own life. Determined to uncover the truth and give Chaeyoung the justice she deserves, she secretly reopens the investigation herself. Using her position in the school journalism club as cover, she begins interviewing students, collecting clues, and piecing together the lies hidden within the halls of her prestigious high school.

But solving a murder case alone is never easy.

Everything changes when Sim Jaeyun (Jake), a mysterious transfer student from Australia, becomes her new seatmate. Smart, observant, and impossible to ignore, Jake quickly notices Hyejung's suspicious behavior and insists on helping her. What starts as simple curiosity soon turns into something deeper-because Jake finds himself drawn to the quiet girl chasing justice, and the more time they spend together, the harder it becomes to deny his growing feelings for her.

As hidden secrets begin to surface, dangerous truths unravel, and the line between friend and suspect blurs, Hyejung and Jake find themselves pulled into a chilling mystery that someone will do anything to keep buried.

In a school filled with whispers, lies, and shadows from the past, can they uncover the truth before history repeats itself?

Or will the rooftop claim another victim?
