In a quiet apartment, the tension between mother and son reaches a breaking point. 俊一君, a high school student preparing for university entrance exams, is constantly at odds with his mother, who has always expected the best from him. She is determined to secure his future, pushing him relentlessly to study and to succeed. But behind the strict expectations lies a hidden truth — a secret that has been growing stronger with each passing day.
For years, 俊一君 has been stealing his mother’s undergarments, a habit that has gone unnoticed until now. What starts as a simple act of mischief turns into a deeper, more intimate connection — one that neither of them can ignore. As the mother’s patience wears thin, the pressure mounts, and the lines between mother and son begin to blur.
One night, the mother discovers the extent of 俊一君’s secret — and with it, a new kind of relationship begins to unfold. What starts as a mother’s attempt to guide her son toward success turns into a passionate, almost obsessive bond. The two of them become entangled in a cycle of intimacy and desire, each trying to fulfill the other’s needs — and their own.
But the secret cannot stay hidden forever. 俊一君’s actions eventually lead to a dramatic confrontation, one that results in a life-changing event. After a year of separation, he returns home, bringing with him a new sense of purpose — and a desire to reunite with the mother who has always believed in him.
As the two of them reconnect, the past comes full circle, and the mother, now more than ever, is ready to embrace the future with open arms. Their bond, once strained by expectations, now grows stronger through love, understanding, and the promise of a new beginning.
