MANILA - "Ito ang happiest stage namin ni Kathryn."

These were the words of "Pangako Sa 'Yo" star Daniel Padilla when asked to describe his relationship with his co-star Kathryn Bernardo on Thursday's episode of "Tonight with Boy Abunda."

"Honestly sa five years namin magkasama, ito na para sa akin ang happiest stage namin ni Kathryn," he said. "Kasi noong last na masaya kami was 16 o 17 kami. Tapos ngayon 'yung maturity namin ito na."

Padilla, however, stopped short in confirming whether he and Bernardo are a couple. But he added that he is not yet willing to be partnered with other actresses for future projects.

"Not yet dahil para sa akin ngayon lang kami ulit nagsisimula ni Kathryn. Hindi mabibigay nang kahit sinong tao iyong binibigay ni Kathryn sa akin," he said.

Bernardo agreed with Padilla. "Ngayon iyong stage na feeling ko kakakilala ko lang ulit sa kanya. Parang 'yung joy nag-doble kasi parang mas nakilala ko na siya, tinanggap na namin iyong isa't isa."

"Lalo na iyong 2015 namin, parang iyong buong year na iyon ay life-learning so alam na namin i-handle 'yung mga bagay," she said.

Asked to describe her relationship with Padilla, she replied: "Kung may tao na aside from my mom na pinakakilala ko, that's DJ."

"Kaya pag malungkot ako o may problema, alam niya agad kung paano ako i-comfort, alagaan. So pag nawala iyong isa, parang ang hirap na kasi nakasanayan mo na nandiyan iyong isa para saluhin ka."

"Pangako Sa 'Yo," which also stars Jodi Sta. Maria and Angelica Panganiban, is set to air its finale on Friday.
