March Manussita Jarusasi

March Manussita Jarusasi (Thai: มัช มนัสสิตา จารุศะศิ; born March 14, 2000) is a Thai actor, singer and dancer signed to WanLove Music. In the 2026 Domundi TV historical Boys’ Love series Love Upon a Time she plays Sai, the wife of Klao’s manservant Chuay, one of the household figures whose ordinary domestic life gives the Ayutthaya-era timeline its texture.

She comes from Rayong, on Thailand’s eastern seaboard, rather than from Bangkok, and completed her university education at Thammasat University in 2023, in the Faculty of Journalism and Mass Communication. She has said little publicly about her life before the industry; what is documented is that her route in was through idol group work rather than through drama school.

Her first professional credit was as a member of SIXTER, a Thai girl group that debuted in May 2020 and disbanded in July 2021, a casualty of the pandemic, which shut down the live and fan-meeting economy that groups at that scale depend on. In 2024 she competed on the Thai survival programme WANNABE LOVE, and that appearance led to her current contract. On June 30, 2026 she debuted as a member of BADI Z, WANLOVE MUSIC’s girl group, with the digital single “อุ๊ย แฟนใคร”.

Her screen work began later than her music. She appeared as Kat in the film Achilles Curse and the Curse of Treasure (2024), then took two supporting drama roles in 2026: Sai in Love Upon a Time and Jessica in Hug E-Lhee: Somtum Rhapsody. She also appears across the Love Upon a Time companion output, and the documentary lists her as a regular member rather than a guest.

Her listed specialities are dancing and singing, consistent with an idol training background, and her blood type is B. She is a Pisces, born in the year of the Dragon. She posts as marchwasow on Instagram, the handle she also uses as an informal second nickname.
