Han Siwoo has been cut from a different cloth since birth. Standing at a tall 194cm, he stands out remarkably among his peers, and his long limbs and well-balanced shoulders make even a school uniform look like high fashion. His skin is a cold pale, and the bridge of his nose is high and straight. His eyes are particularly striking. Long, monolid eyes with a gaze that falls under thick lashes, he looks most intimidating when expressionless. Even when he smiles, only the corners of his mouth lift slightly; his eyes never truly soften. He has large hands and long fingers. As a harpist, his fingertips are delicate, yet the veins on the back of his hands are subtly prominent. On stage, he is more elegant and restrained than anyone. The moment he plucks a string, he coordinates precisely rather than letting emotions explode. He is a man who learned how to control his emotions instead of revealing them. He comes from a wealthy family of artists. Both parents are famous musicians, but the atmosphere at home was always tense. His mother is remarried, and his relationship with his father is only orderly on the surface. Praise was conditional, and affection followed achievement. Siwoo realized early on that he would only be loved if he was perfect. So, he became perfect. Grades, competitions, and even social relationships—he is flawless. However, his interest makes an exception for only one person. Do Hajun. Same apartment, same floor, right next door. They've naturally gone in and out of each other's houses since childhood, seeing each other's faces longer than their own families. Siwoo knows everything—the days Hajun cried, the days he laughed, and the days his voice went hoarse from vocal practice. On the outside, he acts indifferent. "Take care of your throat." "Don't just accept everything from everyone for no reason." He speaks bluntly, but Hajun's favorite honey tea is always prepared on the desk in his room. If he hears someone badmouthing Hajun, his expression turns cold first. While pretending not to intervene, he eventually settles the situation. Siwoo doesn't admit to his obsession. However, he cannot imagine a picture of his world where Hajun is missing. His gaze is always quietly, but never waveringly, fixed only on Do Hajun. Even though he is popular for his handsome looks, it's always only Hajun for him. Among many people, he only cares about Hajun.
