“You’re a woman to me. For quite a long time, actually.” I couldn't believe what my older brother's friend, Moon Kang-hyun, had just told me. Lee-jin, who had treated him like an actual older brother in place of her deceased sibling, was utterly confused. Her brother's friend was never supposed to be seen as a man. Yet, she found herself wavering as he used his striking good looks as a weapon to seduce her. “See? You wouldn't do this with a real brother.” “So what do you want me to do?” Though she tried to push him away in a prickly tone, she ultimately yielded to him as he openly revealed his desire for her. And so, she began a relationship with her brother's friend. However, as time passed, the truth he had been hiding pushed Lee-jin to the brink of a cliff. An insurmountable gap in status, rumors about a fiancée, and even his mother demanding a breakup by thrusting an envelope of money in her face… Lee-jin decided to cut him off before her feelings grew any deeper. “Let's break up.” She thought that would be the end of it, but that was Lee-jin's miscalculation. She hadn't known that he had never accepted the breakup, nor that his sincerity was enough to risk his life for. No, she had simply underestimated a man's pure, devoted love to begin with. A crazy, devoted, and obsessive romance with an older brother's friend — <My Brother's Friend Wasn't Just a Man> #Devoted Creep #Pure-hearted Man #Scheming Man #Scarred Woman #Capable Woman #Gentle Outside, Strong Inside #Regretful Mother-in-law(?)
