Su Yu, a high school student leading a modest life with his father, encounters a significant upheaval when his mother remarries a prosperous man, bringing him face-to-face with his newfound step-brother, Wu Bi. Initially, the two could not be more different; Su Yu, a cold and conceited top student, contrasts sharply with Wu Bi, an unreasonable underachiever. However, their relationship takes an unforeseen twist following an unexpected accident. As they gradually thaw towards one another, their connection deepens. Yet, when a heated confrontation ensues, the true facets of their identities come to light. (Source: MyDramaList) ~~ Adapted from the novel "Are You Addicted?" (你丫上瘾了) by Chai Ji Dan (柴鸡蛋).
