Enjoying a teenage life, second year high school teen Andrew Medina (Nash Aguas) looks forward to maturity.

After a one-night stand results in the unplanned pregnancy of an attractive and brilliant college student named Vanessa Bueno (Ella Cruz), Andrew thinks he committed a huge mistake and takes the responsibilities of teenage fatherhood, changing both his and his love ones' lives.

His father Gilbert (Ariel Rivera) is ready to migrate to the United States for his new job but tells him that he should make the most out of his teenage life and focus on his studies while balancing them to being a new head of the household.

Despite his mere inability to understand algebra, Vanessa Bueno (Ella Cruz), an attractive and popular but brilliant first year college student taking up BS Accountancy in the same school Drew studies in, tutors and aids him.

On Drew's 14th birthday, after a celebration in the Medina household with his friends, the gang goes to a nightclub for a snack but are asked to leave after Vanessa catches them.

Her mother, Sylvia, who is Gilbert's former lover, also reunites with Drew alongside her businessman husband, Arman, and later takes on the role of the school principal.

Sylvia (Agot Isidro) notices this and mistakes it for sexual harassment after asking Drew to find a first-aid kit.
