An eight-year-old sensible cute baby takes the initiative to help his richest-man dad go on blind dates, single-mindedly wanting to find a new mother who is gentle, kind, and treats him sincerely. To sincerely know people, he deliberately changes into plain clothes to test human hearts, encountering one after another utilitarian and calculating blind-date partners who value family background conditions, repeatedly full of disappointment. Until he accidentally meets a kind and enthusiastic truck-driver older sister, who neither looks at clothing nor covets wealth, but is gentle, thoughtful, and treats the child well. Pure goodwill heals the heart, and the cute baby falls in love at a glance and determines [her], opening a warm and healing journey of two-way rushing toward each other.
