Season 1 of You Are My Sunshine premiered on December 18, 2021.

The first impression of Khoa and Truong about each other was not very good, both sides did not want to see each other's faces anymore, but the flow of life pushed them both to appear in the same extra class and from here many situations played out. It caused both of them to change from hate to love at any time. --Prequel of "You are my stupid boy" and Sequel of "Stupid boys, stupid love".
