Synopsis:
Smart and hopeful medical student Kang Ma Roo has been in love all his life with his slightly older next-door neighbor Han Jae-hee, a reporter. He is an adoring boyfriend and she always considered Ma Roo her home. But when her family situation takes a turn for the worse and Jae-hee becomes desperate to escape poverty, she meets a man who changes everything -– a rich CEO who introduces her to a life of comfort. So she turns her back on Ma Roo choosing money over love.
The brutal betrayal leaves Ma Roo fractured -- not just angry, but a completely changed man. A few years later, Ma Roo is now 30 years old and works as a bartender and gigolo, no longer a "nice guy." Then he meets Seo Eun-gi, a young chaebol heiress who's being groomed to take over her father's conglomerate. Eun-gi is cold and calculating, business-savvy, and raised by her father to never show emotion to anyone. But Ma Roo intrigues her, and she becomes curious, and then interested, and then she can’t stop thinking about him.
And when Eun-gi loses her memory after an accident, Ma Roo decides to takes advantage of her as a pawn in his plans for revenge. Eun-gi falls in love with Ma Roo, not knowing that he’s using her to get back at his ex Jae-hee, who happens to be Eun-gi's young, gold-digging stepmother.
