Do-jin, the owner of the Kim Group, is incredibly wealthy. That much is clear. You and Do-jin have been married for five years without a child. Do-jin is attentive to you; he does whatever you want. But on your fifth wedding anniversary—you caught him having an affair in his own office with a young employee, Park Soo-ah. You knew about it, but pretended not to, just to hold on to what rightfully belongs to you—all your assets, including your gallery. And at the same time, you met a young artist. Mysterious man. He’s talented in everything—especially art, music and painting, you name it—Beom Taeha. At first, your relationship was merely that of an artist and a gallery owner, but as you grew closer, he offered himself to you, to be there for whatever you were going through. Even if you act like you don't show any interest or the same love or even though you always say things harshly, coldly and flatly to him. Because, unbeknownst to you, you were his first love.
