Seth Fedelin took to social media to share his birthday message for his onscreen partner, Andrea Brillantes.
The actress is celebrating her 18th birthday this Friday, March 12.
Sharing a photo from their recent photo shoot for Metro magazine, Seth wrote: "Happy 18th to my Ali, @blythe! Wish you the grandest day yet because you deserve the world and more."
In another post, Seth said he was sorry that he couldn't be there to celebrate with Andrea on her special day.
"Sensya na wala ako mismo sa araw ng bday mo. Nakakalungkot," he wrote, without giving further details.
The actor went on: "Sana ngayong 18 ka na hindi ka magbago kung ano ka sa mga tao. Maging bait ka palagi ha. At Ali wish ko sana lahat ng pangarap mo matupad mo as in lahat lahat at sana ako ang maging saksi mo doon sa mga pangarap mo.
"'Pag okay na lahat Ali babawi ako kasi di ako makakapunta sa bday mo eh. HAPPY BIRTHDAY ALI KO. DITO LANG AKO PALAGI HA," he added.
Andrea and Seth, now both 18, have been an onscreen couple since 2019.
Dubbed "SethDrea", their tandem first rose to popularity when they first co-starred in the hit afternoon drama Kadenang Ginto.
Despite not being an official couple, Seth and Andrea do not shy away from declaring that they have a mutual admiration for each other.
In a previous interview, Andrea admitted that Seth is “very special” to her.
“Bilang tao, sobrang hinahangaan ko siya. Bilang si Seth, mahal ko po 'yung pagkatao niya. Gusto ko po siya suportahan. Kapag narating niya 'yung pangarap niya, gusto ko nandoon din ako,” she said.
As for Seth, he said he wants to have the actress be part of his life for a very long time. However, he said they are not rushing to take their friendship to the next level.
“Kasi kaming dalawa, alam namin 'yung priority namin. Wala sa isip namin iyan. Sa akin, alam ko kasi na sige ako kapag ako na-in love sa 'yo at naisipan ko talagang kunin ka, gagawin ko kung naramdaman ko ‘yon. Pero ngayon siguro, wala pa sa isip naming dalawa 'yun kasi may goal kami,” he said.
Andrea and Seth are set to co-star anew in the ABS-CBN inspirational series Huwag Kang Mangamba, along with their The Gold Squad peers Francine Diaz and Kyle Echarri.
The show will start airing on March 22, at 8:40 p.m., and will be available on Kapamilya Channel, Kapamilya Online Live, A2Z Channel 11, and iWant TFC.
