Born on October 18, 2004, in Bangkok, Thailand, he is widely recognized for his leading roles in Thai television dramas, particularly his portrayal of Gun in My School President and Li Ming in Moonlight Chicken. He first entered the public eye after winning a national youth talent competition before transitioning into screen acting and music.

Nattawat spent his childhood in Bangkok as the eldest child of a Thai Chinese father and a mother from Sakon Nakhon province. Encouraged by his mother to pursue entertainment from an early age, he appeared in his first beverage commercial at age three. While attending Saint Gabriel's College, he actively participated in extracurriculars, serving as the captain of the school football team and performing in a school musical. He earned his high school diploma early by passing the Grade 12 equivalency exam while in the tenth grade, later enrolling at Chulalongkorn University to study business and technology law in an international program.

His professional journey began in 2019 when he competed in the Smart Boy modeling contest. Later that year, at fifteen, he won the Thailand School Star 2019 competition hosted by GMMTV, earning an exclusive contract with the agency. Nattawat made his television drama debut in 2021 playing Glakao Jundee in F4 Thailand: Boys Over Flowers, the local adaptation of a popular Japanese manga series.

He took singing lessons for the role, which featured musical performances by the cast. Shortly after, he starred as Li Ming in Moonlight Chicken (2023). His screen partnership with co-star Norawit Titicharoenrak, known as Gemini, led to the formation of their popular duo GeminiFourth. The pair earned several industry honors, including awards from GQ Men of the Year 2023 and the 33rd Seoul Music Awards, and launched joint music singles and international fan tours.

Expanding his musical footprint, Nattawat joined Riser Music in early 2024, releasing several solo tracks and collaborations with artists such as UrboyTJ and Hye of Paper Planes.
