Born into the prominent Lee family, Yeon has always enjoyed a privileged and comfortable life. However, his achievements and competence pale in comparison to his older adopted brother, Kangwoo. This disparity fuels Yeon's constant, barbed mockery toward him. While Kangwoo usually endures the insults in silence, Yeon finally pushes him too far with a particularly offensive remark. When Kangwoo unexpectedly extends an invitation to his bedroom, Yeon's sheer arrogance compels him to accept. What Yeon doesn't realize is that his big brother is about to deliver a very intense and unforgettable lesson. ⓒ SaeOngji, BOKSUNG-A, btlz / DAYS ENTER Corp. All rights reserved.
