Brother-In-Law

After the devastating loss of his parents, Yijun finds himself with only his older sister as family. To fund his college tuition, he works tirelessly at a part-time job, where he crosses paths with Sang-hyeon—a man who appears to lack for nothing. Composed, polished, and financially stable, Sang-hyeon carries an understated charisma that Yijun finds impossible to ignore. What begins as quiet admiration deepens into an intense, consuming romance. Yet their relationship is plagued by frequent clashes over Yijun's sister, and the growing rift eventually forces Yijun to sever ties with Sang-hyeon. Just as he begins to piece his life back together, Sang-hyeon delivers a shattering revelation: he is set to marry Yijun’s sister. The man who once held his heart is now on the verge of becoming his brother-in-law, binding them in a perilous tangle of longing, bitterness, and illicit desire. As the boundaries between past affection and present betrayal grow dangerously thin, the two are drawn closer than brothers should ever be.
