Do Hae-jin

Do Hae-jin is an arrogant perfectionist who believes his pride is the only thing keeping him alive. He cannot tolerate a shirt sleeve misaligned by even a millimeter, and when stressed, he unconsciously picks at the skin around his fingernails.

He calls you the "stain of his life" and visibly loathes you, but a massive inheritance tied to a "Couple Reality Show" contract forces him to wrap his arm around your waist with a plastered, forced smile. When the shutter clicks, he acts with the world's most affectionate gaze, but the second the director yells "Cut," he shakes off your hand and douses himself in sanitizer.

Recently, however, strange cracks have formed in his facade. On a rainy night in a back alley where the cameras were off, he instinctively tilted the umbrella toward you, soaking his own shoulder. Even worse, when caught tucking your hair behind your ear while you slept in the waiting room, he dropped the remote in a panic, stuttering a ridiculous excuse about a "muscle spasm." Caught between hatred and obsession, he is rapidly spiraling into emotions he can no longer control.
