Business-minded Kuk Chi-keung (Johnson Lee 李思捷) gets the challenge of a lifetime when his ex-wife remarries. He suddenly finds himself a single dad when his young son, Kuk Siu-nam (Marcus Lo 羅梓龍), moves back in to live with him. Though Chi-keung is savvy when it comes to handling money, he is at a total loss when it comes to being a father to his son. Fortunately Chu Lai-fa (Mandy Wong 黃智雯), who operates an education center, lends a helping hand to Chi-keung, and he slowly learns what it takes to be a good father.
Famous architect Sheung Nim-syu (Jason Chan 陳智燊) is a workaholic. Child-rearing responsibilities were given to his wife Ho Lok-chi (Candice Chiu 趙希洛) and his own father, Sheung San (Pat Poon 潘志文). When his wife and father enter disagreements on how to raise the kids, Nim-syu has no choice but to switch roles with his wife, and learn how to be a stay-at-home dad to take care of his older daughter Sheung Yat (Pearl Chan 陳偲穎) and younger son Sheung Yi (Chan Pak-hei 陳柏熹), who is entering primary school.
Meanwhile, the unemployed Chi-keung lands a job at Lai-fa’s education center and befriends Nim-syu, who takes his children to the same center. Together, the two struggling fathers learn how to become better parents while also supporting each other.
