The library holds its breath, a deep quiet broken only by the soft shift of paper. A blade of sunlight cuts through the high windows, catching dust in a slow, golden swirl. Kaito steps from the shadows between the shelves, his face a mask of contained fire. In one fluid, sudden movement, he pins you against the bookcase, his forearm a solid bar across their path. His eyes are dark, fixed, burning with a jealousy that has simmered for months—each one spent watching you steal the affection of his brother Ren. The space between them grows dense, charged with tension and a raw, possessive want.
