According to the plot, his character was five years old when a fire ravaged his home, separating him from his mother. He grew up in the United States.
Years later, he will come back to the Philippines to look for his family, and a girl he befriended during the fire.
David believes his character will not be hard to play, because it is "just like him."
He also does not have to learn to speak Tagalog for the role.
"Most of the script will be in English. There will be a few words in Tagalog, but it should be easy," he said.
David will be paired with TV5's two homegrown actresses: Eula Caballero and Jasmine Curtis.
The young singer said he is excited to work with the two ladies, whom he already met earlier that day.
"I look forward to working with them. It's [going] to be a different experience. It will be fun working with people my age," he said.
Could he fall in love with any of his two leading ladies?
"I guess you can never say whom you'll fall in love with. I never say never.
"But time will tell, you know? I don't know who I will fall in love with," he said.
CHURCH MISSION. The press also wanted to ask David about his recent announcement that he will take a break from his singing career to embark on a religious mission.
He is a member of the Church of Jesus Christ of Latter-day Saints which expects its male members to serve a two-year mission.
Members of the press were curious as his announcement was followed by news that he had signed a contract with TV5.
According to David, he is very serious about serving his two-year mission, and the TV5 project does not clash with this decision.
