In the scene, Seon-ho clutches his chest as if overcome with emotion, then flashes a playful wink and smile. The heartwarming moment quickly sparked a TikTok trend, with users around the world imitating the gesture to convey affection or admiration. The challenge has since gained widespread popularity on the platform.

Fans online were quick to react to Piolo's video.

"Dalawa na tayo nakangiti ngayon," one fan commented.

When Life Gives You Tangerines tells the story of "a spirited girl and a steadfast boy's island story [which] blossoms into a lifelong tale of setbacks and triumphs, proving love endures across time," asper its IMDb page.

Seon-ho played the role of artist Park Chung-seob, the love interest of IU's character, Yang Geum Myeong.

Meanwhile, Piolo recently headlined the Kapamilya series Pamilya Sagrado.

"Nung in-offer ‘tong ‘Pamilya Sagrado,’ I couldn’t say ‘no’ to it, and I wanna be part of a show that tells a good story," he recounted in a previous interview with Tao Po.

Piolo emphasized his desire to embrace a wide range of characters at this point in his career.

"I just want variety. I love variety. I mean, I still have the same excitement, nervousness, kilig. Everything that I felt when I was starting until now. I enjoy the pressure, I enjoy the challenge," he said.

The actor went on: "I think, I’m constantly transitioning from being a matinee idol to a more serious actor taking on dark roles. I think, it’s inevitable and also, at the same time, a privilege for you to be able to diversify into different genres and characters. Ang ganda lang nung habang tumatanda ka, nagkakaroon ka ng iba’t ibang choices sa role mo and it never ends. I thought I was gonna retire at 40. Only God knows what I’m gonna do next."
