Fourth Nattawat Jirochtikul
BIOGRAPHY
Nattawat Jirochtikul (Thai: ณัฐวรรธน์ จิโรชน์ธิกุล; born October 18, 2004), known by his nickname Fourth, is a Thai actor and singer signed to GMMTV and Riser Music.
He was educated at Saint Gabriel’s College, completing his studies there early via a GED equivalency, and is currently pursuing a Bachelor of Laws at Chulalongkorn University.
His route into the industry ran through Thailand School Star in 2019, the GMMTV talent competition. On screen he started in supporting parts, among them a school junior to the leads in Bad Buddy (2021), before landing his first credited role as Kla Kao in F4 Thailand: Boys Over Flowers (2021). He rose to wider prominence opposite Gemini Norawit Titicharoenrak as Gun in My School President (2022), and the pair went on to headline Midnight Series: Moonlight Chicken (2023) as Li Ming, the project that established the on-screen pairing “GeminiFourth” and its fandom, known as “Khunnoo.”
He continued acting in My Love Mix-Up! (2024) as Atom, before reuniting with Gemini for the lead role of Tanrak in Ticket to Heaven (2026), their first pairing as leads since Moonlight Chicken. He is also set to appear in Kijsada Paradise (2026) as Taek.
Work in front of a camera started early. He appeared in a commercial as a small child and, at fourteen, entered the Smart Boy 2019 modelling contest, after which he was scouted for a telecom advertisement. At school he captained the football team and took part in the stage musical Sombat Mom Chuli: The Musical.
The screen list has more in it than the leads. He reprised Gun for two episodes of the anthology series Our Skyy 2 in May 2023, and the same year he took a supporting role as Tae in the film Nednari. Kijsada Paradise, directed by Mike Phontharis Chotkijsadarsopon, is a horror film in which Taek leads a group of friends exploring an abandoned water park, with Yorch Yongsin among the cast. He has also lent his voice to the Thai dub of Disney and Pixar’s Elio (2025), and a role as Prince Chom Han in Scarlet Heart Thailand was announced in April 2024.
In music, he became a Riser Music artist in 2024 after a run of releases through GMMTV Records. His first single under the label, “Candidate” (Thai title: เทคะแนน), came out on February 20, 2024, and a second single followed that August. Earlier, his 2023 single “Please Be Mine” had introduced him as a solo artist, and later releases include “Doubtless” with Kow of Fellow Fellow in 2025, “Side to Side” featuring Mabelz of Pixxie the same year and “Every Single Day” in 2026. With Gemini he recorded the city-pop duet “You’re Blushing?” in 2023 and the pop R&B track “Is This Love?” in 2025. Their opening theme for My Love Mix-Up!, “Re-Move On”, was recognised for best theme song at the Asian Academy Creative Awards and for its soundtrack at the Y Entertain and Y Universe awards.
On stage, the pair have headlined the concerts My Turn (August 2023) and Run the World (August and September 2024) at Impact Arena, followed by an Asia tour that ended in Osaka on June 29, 2025, and the A.W.A.K.E concert later that summer. Fourth and Gemini also took part in the Riser Music showcase The First Rise at Impact Arena in February 2026. A stage musical, Love of Siam, lists him as Mew for a December 2026 run at the Muangthai Rachadalai Theatre. Outside performing, he started the clothing line Numone in February 2023.
He has received the Golden Kinnaree Awards’ Popular Couple Artists prize (2023, with Gemini Norawit Titicharoenrak) and recognition at the GQ Thailand Men of the Year and Kazz Awards (2023), along with the Thai Best Artist award at the 33rd Seoul Music Awards in 2024.
His credits stack up quickly. Bad Buddy and F4 Thailand both date from 2021, yet by 2022 he was a lead, and by 2024 he was also releasing records under Riser Music. That makes three kinds of work, supporting cast member, lead and recording artist, inside four years.
Fourth has starred opposite Gemini Norawit Titicharoenrak in three projects since 2022.
After My School President and Moonlight Chicken, the pair lead Ticket to Heaven, with Fourth as Tanrak.
The spacing of those three projects is uneven. The first two came in consecutive years, 2022 and 2023, and the third in 2026. Between them he worked without Gemini on My Love Mix-Up! as Atom and released both of his Riser Music singles, so the gap is filled with a different kind of role and with music. His awards came in the same year as Moonlight Chicken, 2023, which means the Golden Kinnaree, Kazz and GQ recognition all landed within twelve months of the pairing first leading a series. Tanrak in 2026 is also the third distinct lead name in his list, after Gun and Li Ming.
In my view, what sets Fourth apart is how many things he keeps running at once: a law degree, a recording career, concert stages and a film slate that now includes a horror feature. What stayed with me is the reach of the parts themselves, from a high school music club leader to a seminary student to the head of a group of friends in an abandoned park. If you are new to his work, I would start with My School President for the pairing at its most playful, then move to Ticket to Heaven to see how much heavier his material has become.
