On Instagram, Marvin Agustin shared his birthday message for his twin sons Santiago and Sebastian, who just turned 15 years old.
The actor-entrepreneur began his post by saying how he has always felt nervous about having the responsibility of fatherhood since entering it 15 years ago.
"15 years dumating kayo sa buhay namin. 15 years na din akong kabado kung tama at maayos ba ang trabaho ko bilang tatay," he said. "Pero hindi 'yun dapat intindihin, yan ang responsibilidad na pinasok ko."
He went on by saying that he will always be there for them in their life, which he believes is their self-fought journey.
"Mas gusto kong makilala niyo sarili niyo at walang ibang magsabi sa inyo kung ano at dapat nyong piliin sa kaligayahan niyo at maaring kaligayahan na mabibigay niyo sa iba," Marvin said.
Marvin, then, thanked his boys for the opportunity and experience of fatherhood they have given him.
"Mahirap ang pinagdadaanan natin ngayon pero masaya ako sa maliliit na bagay na napagtatawanan at ikinaliligaya pa din natin," he explained.
He, then, turned his readers' attention to the message's accompanying photos of his sons' transformations from babies to growing teenagers.
"Swipe right, ang mga anghel 15 years ago ay mga tao na lalaban sa mga gusto nilang tahakin sa buhay," Marvin said.
"Happy birthday handsomes! Kung hindi niyo maintindihan ang mga sinabi ko, ask your mom. She will translate in English," he concluded in jest.
It was back in 2005 when Marvin welcomed his twin sons with then-girlfriend Tetet Dy.
The two have since separated, but remained good friends for the sake of their children.
