Luhan's grandfather has just passed away, leaving a scandal in his wake. When it is revealed that he kept a mistress even at seventy-three years old, Luhan is shocked. He is even more confounded to find a boy of three years left abandoned on the front porch of the funeral, holding a letter that entails how he was borne out of wedlock - an illegitimate child of his grandfather and mistress. Wu Fan, his uncle sixteen years his junior, is rejected at once, but Luhan takes him in and raises him with much struggles. Nonetheless, he presses on and the two grow closer than ever. Now a teenager, Wu Fan discovers his 'dad' is actually his nephew, despite him being older. At first, Luhan worries his secret will sour their bond, but he eventually discovers it has just given Wu Fan the upper hand.
