2022–2023: Breakthrough with My School President and Moonlight Chicken
Fourth starred in his first lead role in the boys' love series My School President (2022), as Gun, who is the leader of his high school music club and the love interest of the student council president, Tinn, played by Gemini. The show takes a musical approach by incorporating songs performed by the cast into the storytelling. Fourth began taking singing lessons for his role, sharing that he went from being shy and feeling awkward singing in front of a crowd, to enjoying performing and singing along with fans. Fourth later reprised his role as Gun in May 2023 in two episodes of the anthology series Our Skyy 2.
While My School President was still ongoing, Moonlight Chicken aired in early 2023, where Fourth played Li Ming, the nephew of Uncle Jim (Pirapat Watthanasetsiri) and the love interest of Heart, also played by Gemini.
The explosive popularity of My School President and Moonlight Chicken propelled Gemini and Fourth to significant fame and the duo quickly became popular as "GeminiFourth". Their fandom was given the name "Khunnoo" (คุณหนู), a title used to address a 'young master', heard in episode 4 of My School President. The cast of My School President went on to perform live on stage and met fans across Asia. Gemini and Fourth also gained recognition for their roles, receiving awards such as Popular Couple Artists at the Golden Kinnaree Awards, Hottest Artist Award at the Kazz Awards, Breakthrough Actors from GQ Men of the Year 2023, and Thai Best Artist at the 33rd Seoul Music Awards.
In March 2023, following the success of My School President, Gemini and Fourth went on to further establish themselves as artists with the release of their single "เขินให้หน่อย (You're Blushing?)", a city pop track co-produced by Now of Mirrr and songwriter Third of Tilly Birds. In August, Fourth released his first solo single "อยู่เฉย ๆ ก็น่ารัก (Please Be Mine)".
In June 2023, Fourth and Gemini participated in the Love Out Loud Fan Fest 2023: Lovolution concert alongside other GMMTV artists. In August, they headlined their first concert together, Gemini Fourth My Turn Concert. Due to overwhelming interest in concert tickets, a second date was added.
