After her mother remarries, Lee Hyeon-ah finds herself with a new stepfather—Cha Kangjun, a man who is young, calm, and almost disturbingly perfect. They aren’t related by blood, and Hyeon-ah is already an adult, yet after the wedding, Kangjun’s attention toward her begins to grow more intense.
When her sick mother leaves the country for medical treatment, the house turns into a closed-off world filled with heavy silences, subtle threats, and boundaries that slowly begin to disappear.
Caught between fear, dependence, and a confusing pull she can’t quite explain, Hyeon-ah is forced to face just how far obsession can go when love, power, and secrecy twist into something truly dangerous.
