Thitiwat Ritprasert (Thai: ฐิติวัฒน์ ฤทธิ์ประเสริฐ; born 26 March 1997), nicknamed Ohm (Thai: โอห์ม), is a Thai actor and model. He is best known for his roles in Until We Meet Again (2019).
Early life and education
Thitiwat was born in Chiang Rai, Thailand. He graduated from Rajamangala University of Technology Thanyaburi with a bachelor's degree in the Faculty of Mass Communication Technology.[1]
Career
Thitiwat entered the entertainment industry by participating in the CH8 Asia New Star Model Contest Face of Thailand 2016,[2] where he won the competition. He also received a special award at the Asia Model Festival FACE of ASIA 2016. [3]
In 2017, he made his acting debut in the television drama Jai Luang on Channel 8.
In 2019, his popularity increased significantly after portraying the lead role as Dean Ratthanon Wongnate, a university student, the swimming club president, and one of the central characters whose connection to a past-life romance drives the narrative in the television series Until We Meet Again, alongside Natouch Siripongthon.[4][5] The series is based on the novel The Red Thread by Lazy Sheep.[6]
On September 1, 2024, he joined the production and talent agency GMMTV.[7] This move marked his departure from his former company, and at that time his last series under the previous studio had not yet been released or aired—leaving fans uncertain whether it would ever be broadcast. Only weeks after the transfer, his former network, Channel 8, announced the upcoming airing of that final project: Suek Saneha Kraithong Chalawan (also known as Love of the Two Realms). The series draws inspiration from Thai folklore “Kraithong,” depicting the story of Chalawan—the powerful crocodile king who becomes infatuated with the daughters of a wealthy man, Tapaokaew and Tapaothong. Driven by desire, he abducts the sisters and brings them to his underwater palace. Chalawan is portrayed as a formidable and nearly unbeatable antagonist—until the warrior Kraithong arrives, defeats the crocodile king, and rescues the sisters, who later become his wives. Although Chalawan was a villain in the series, Thitiwat’s portrayal received widespread praise. Viewers admired his performance, and he gained new fans, with many affectionately referring to him as “Chalawan” in online spaces and everyday conversation—demonstrating how the character left a lasting impact despite being an antagonist.
On November 26, 2024, Thitiwat was announced as part of the main cast of My Romance Scammer, alongside Panachai Sriariyarungruang and Jiruntanin Trairattanayon. He was initially announced to be paired with Jeeratch Wongpian for the series. On August 19, 2025, it was officially confirmed that Poon Mitpakdee [8] would replace Jeeratch in the main role and become Thitiwat’s on-screen partner. The series later aired on February 1, 2026, marking the pair’s first on-screen project together following the casting announcement.
On November 25, 2025, Thitiwat and Poon were announced as part of the upcoming GMMTV 2026 series Cupid's Ghost (Thai: ผีผลักให้รักคุณ) in supporting roles. They appear alongside lead actors Pirapat Watthanasetsiri and Sahaphap Wongratch, with Poon Sutarom also in a supporting role.
