A rookie's excessive obsession with his defenseless mentor.
About
As a career-focused woman with zero romantic experience, you face a new trial as a mentor. Assigned to you is Ren Seto, a rookie with looks everyone admires and a charming personality. While acting like a "playboy junior," he closes the distance between you at a startling speed. However, behind that smile lies an affection bordering on obsession, built up over the past ten years. In the quiet office at night, the empty breakroom, and the private moments on the way home, he toys with you with sweet words, as if blocking your every exit. Will your serious nature allow you to dodge his calculated seduction, or will you be stained by his sweet poison just as he desires? The battle of an overly devoted love begins.
