GMMTV introduced Sea Dechchart Tasilp and Keen Suvijak Piyanopharoj as a pair in March 2024, when Thai entertainment press ran them together as the two newcomers cast in Only Boo!. Neither had carried a series before. Sea had signed with GMMTV in 2023, after a year with Sol Entertainment, and had a single guest appearance behind him. Keen had placed seventh on the survival programme Project Alpha in 2023, signed with GMMTV at the end of it, and had a supporting part in My Tempo. Their first leading roles were each other’s.

The label SeaKeen is not a fan coinage the studio quietly allowed. GMMTV writes it itself. The company’s own account announced the SeaKeen 1st FanMeeting in Taipei for 17 August 2024, and the two later events carry the same construction: SeaKeen FanMeeting in Thailand on 28 April 2026 and SeaKeen 2nd FanMeeting in Taipei on 3 May 2026. The order of the two names has not changed since the first announcement, which is worth stating plainly, because on a lot of pairing pages that order is guessed.

What the pairing has done since is not what a debut pair usually does, which is repeat the thing that worked. Only Boo! (2024) was a school romance built around an idol contract. Head 2 Head (2025) recast them as Jirakan, called Jerome, and Thichayothin, called Jinn. WEIRDO-101 (2026) moved them off GMM 25 to One 31, with Sea as an astronomy club student and Keen as a judo team student with no plan for anything. Three leading pairings in three years, across two networks.

They record together as well as act together. “พี่(อย่า)แกง (Don’t Be Fooled)” came out of the Only Boo! soundtrack in 2024, “คิดว่าไม่ แต่ดันใช่ (Turns Out It’s You)” out of Head 2 Head in 2025, and “โน้ม (Gravity)” out of WEIRDO-101 in 2026, one duet per series. Keen has a separate music career alongside it: he debuted in the boy group Clo’ver under Riser Music in November 2025, with Ashi Peerakan, who played Payos in Only Boo!, among the members.

Sea Dechchart and Keen Suvijak were cast in their first leading roles at the same time, in the same series, which is unusual even at a studio that pairs actors as a matter of routine. The pairing runs on contrast rather than on symmetry: Sea plays quiet and lets a scene come to him, Keen plays the one who speaks first. Across the three series they have led, which of the two does the pursuing has been reset each time, and the paired soundtrack duet has become a fixture of every one of them.
