MANILA -- "Kung sino 'yong alam niyang makakapagpatibok ng puso niya, at sisiguraduhing hindi lang siya ang mamahalin, at mamahalin din 'yong kabuuan niya -- 'yong pamilya niya at mga mahal niya sa buhay."

This was the short yet meaningful love advice of actor Rommel Padilla to his son, Daniel.

On Friday, the older Padilla guested on the morning talk show "Magandang Buhay" for their special Father's Day episode, where he was reunited with his former lover and Daniel's mother, Karla Estrada.

According to Padilla, his son has always been very obedient of him despite his rising popularity as a young heartthrob.

"Mabait na bata si DJ [Daniel], marespeto. 'Yong lahat naman ng sinabi namin kung paano maging mabuting anak, lahat naman sinunod niya," he said.

The older Padilla added that he is very proud of his 21-year-old son, who remained humble despite his countless achievements.

"Hindi masusukat [ang pagiging proud ko] kasi nakita ko sa kanya na kahit nandoon na siya, at alam kong lalaki pa siya, e ganun din naman din 'yong pagyuko niya -- sa pamilya, sa mommy niya, sa akin, sa mga kapatid niya, especially sa mga taong nagmamahal sa kanya," he said.

He also said that he is happy that his son is learning how to be "makatao" at an early age.

Daniel is romantically linked to his on-screen partner, Kathryn Bernardo.
