They've been friends for 8 years before taking their relationship up a notch.
So it's no surprise that Angel Locsin and Neil Arce were a bit hesitant in doing so, especially because there's a risk of losing their friendship should they have a huge fallout.
In an interview on "Tonight With Boy Abunda" on Friday, the "La Luna Sangre" star shared the one promise she and Arce made to one another before stepping forward with their romance.
"Alam kasi namin na hindi siya basta-basta pinapasok kasi ayaw namin masira iyong friendship," she said, adding: "So ang naging usapan, 'Kung anuman ang mangyari dito sa napaka-exciting na journey natin, basta hindi tayo puwede mag-away.'"
Locsin described Arce as her "source of happiness."
"Hindi rin po namin alam kung paano nagsimula ang lahat pero we're happy. Nagpapasalamat ako na naging ganito iyong relationship namin," she acknowledged.
It was last month when Locsin first opened up about a possible romance with Arce, a film producer.
