Riser Music is making serious waves—ensuring Thailand isn’t just part of the Asian music boom in the West, but leading it. From the celestial pop of NANON’s chart-topping debut Secrets of the Universe to the meteoric rise of boy group LYKN fresh off their smash-hit BL drama ThamePo: Heart Skips a Beat, international fans just can’t get enough.

Now, Riser is turning up the heat with the official debut of JASP.ER—a four-member vocal and dance unit made up of beloved BL drama veterans. That’s right: Joong Archen (จุง), Aou Thanaboon (อู๋), Santa Pongsapak (แซนต้า), and Pond Naravit (ปอนด์) aren’t just actors anymore—they’re full-fledged idols.

The buzz started on 13 December 2024, when RISER teased a mysterious new artist reveal. Speculation ran wild, especially when hints dropped that it might be a group. The rumors proved true—Project JASP.ER was born, blending star power with idol energy.

Their debut single, แรงอีกนิด (SADISTIC), doesn’t hold back. It’s bold, breathy, and unapologetically sexy—with Pond’s deep baritone anchoring the track in pure, sweat-inducing seduction.

With talent, charm, and serious stage presence, the members of JASP.ER are more than just pretty faced heartthrobs. Here’s everything you need to know about the quartet taking center stage.

Joong Archen (จุง) – The Globe-trotting Charmer

Born Rachen Lueangthong, Archen’s story reads like a K-drama with a passport. At just eight years old, he moved from Thailand to Türkiye with his mother and stepfather, spending nearly a decade abroad before returning to Thailand at sixteen to finish his education. With a multicultural upbringing and smoldering screen presence, Archen quickly caught the industry’s eye.

He made his acting debut in the buzzworthy—and controversial—2 Moons 2, stepping into the spotlight with confidence and charisma. Before JASP.ER, he was part of not one but two other idol groups: OXQ under Motive Village and Insight Rookies under Insight Entertainment.

Since signing with GMMTV in September 2021, Archen has proven he’s more than just a pretty face with standout roles in fan-favorite series like Star and Sky: Sky in Your Heart, Hidden Agenda, and the criminally edgy The Heart Killers – which is arguably one his best roles to-date.

Aou Thanaboon (อู๋) – Wicked Spice

Before stealing hearts (and headlines) in the 2024 smash hit We Are, Thanaboon Kiatniran was quietly building a résumé of scene-stealing support roles in some of GMMTV’s biggest dramas. You’ve seen him in Enchanté, Vice Versa, The Eclipse, Be My Favorite, and the criminally underrated Midnight Museum.

There’s an innocent charm to Aou that makes him romantically dangerous—in all the best ways. He’s the guy who’ll smile shyly one second and have you breathless the next. Because beneath that boy-next-door sweetness? The man’s got moves that make hearts race and clothing fall to the floor.

Santa Pongsapak (แซนต้า) – The Breakout Boyfriend

A fresh face in the GMMTV lineup, Pongsapak Udompoch—better known as Santa—is anything but a rookie. Formerly signed to Studio Wabi Sabi, Santa cut his teeth on some of the most beloved BL dramas in recent memory, including  7 Project, War of Y, My Only 12%, and the Miquel to Until We Meet Again – the greatest BL drama of all time – Between Us.

When Studio Wabi Sabi shifted from managing talent to focusing strictly on production in April 2024, Santa didn’t waste time. He joined the exodus of rising stars making the leap to GMMTV, making his official debut in Perfect 10 Liners, with his BL parter Perth (Tanapon Sukumpantanasan) – who was also featured in Until We Meet Again.

Pond Naravit (ปอนด์) – Prince Charming.

In 2020, Naravit Lertratkosum didn’t just win a competition—he won the nation’s heart. Crowned one of the winners of the third Go On Girl & Guy Star Search by Clean & Clear, Pond’s fresh-faced charm and magnetic presence lead him to be signed to GMMTV.

It didn’t take long for him to make a splash. His official debut came in 2021 with the wildly popular college rom-com Fish Upon the Sky—written by the iconic JittiRain—where his blend of boyish mischief and undeniable warmth turned him into an overnight heartsotopper. Other roles include Never Let Me Go, We Are, and the currently airing Leap Day.

During his university life, Pond was crowned the hottest guy of the Faculty of Engineering at King Mongkut’s Institute of Technology Ladkrabang where he is currently studying Biomedical Engineering.

His deep baritone voice and his angelic good looks make him a fan favorite (me, I’m fan).

After officially transitioning from a project group to a debuted act, the group’s first official single ถอด (TAKE IT OFF) amassed more than a million views in its first week of release.
