The Genesis of Their Collaboration: From "My Ambulance" to Regional Stardom
The professional paths of Billkin and PP Krit first intertwined significantly with their roles in the Thai television series "My Ambulance" (2019). Billkin portrayed Dr. Tao, and PP Krit took on the role of Tewkao. Their on-screen pairing, often categorized within the "boys' love" (BL) genre, resonated strongly with viewers, sparking a considerable amount of attention and laying the groundwork for future collaborations. This initial success was a crucial stepping stone for both artists, introducing them to a wider audience and establishing their undeniable chemistry.
The success of "My Ambulance" paved the way for their leading roles in the highly acclaimed Thai series "I Told Sunset About You" (2020). In this coming-of-age drama, Billkin played Teh, and PP Krit portrayed Oh-aew. The narrative followed their journey from childhood friends to rivals who, upon reuniting in their senior year of high school while preparing for university admissions, begin to explore a deeper connection beyond friendship. The series was lauded for its sensitive portrayal of young love and self-discovery, and its popularity led to a direct continuation, "I Promised You The Moon" (2021), which further explored the complexities of their relationship.

While Billkin had a recognized presence in the Thai acting scene prior to these projects, it was his role in the feature film "How to Make Millions Before Grandma Dies" (2023) that propelled him to significant regional fame.

This role marked a major milestone, extending his reach beyond the dedicated fanbase of BL dramas to a broader cinematic audience.

He also worked as a catwalk model in "Boys of Bangkok 2017" at the Emquartier.
