Ploy Shompoo

Ployshompoo Supasap, known professionally as Jan, is a Thai actress, singer, and model under GMMTV. She first gained attention through a beverage company talent competition in 2014 that led to a commercial with Girls' Generation's Taeyeon. Her breakout role as Praepailin in the 2016 series SOTUS established her as a rising talent in Thai television. Jan also served as the leader of the project girl group SIZZY from 2019 until its disbandment in 2024. She is recognized for her versatility across genres, from dramatic roles like the villain Tida in Who Are You (2020), which earned her a Zoom Dara Award, to lighter parts in series such as Cherry Magic and Peaceful Property. With over 2.2 million Instagram followers, she maintains an active social media presence while continuing to take on new acting projects. Her academic background in Philosophy, Politics, and Economics from Thammasat University sets her apart in the entertainment industry. [edit]

Jan grew up in Bangkok and attended Bodindecha (Sing Singhaseni) School. In 2014, while still a student, she entered a nationwide talent search organized by the beverage brand B-ing and won. The prize was an appearance in a commercial alongside Girls' Generation member Kim Taeyeon, which gave her early exposure to the entertainment industry. She went on to study Philosophy, Politics, and Economics at Thammasat University, graduating in 2017. Her first acting role came in 2016 with a guest part in the series Senior Secret Love: Puppy Honey, followed by a supporting role in SOTUS later that year. [edit]

Jan's role as Praepailin in SOTUS (2016) and its sequel SOTUS S (2017) made her a recognizable face in Thai BL and teen dramas. She continued with roles in Slam Dance (2017) and the web series YOUniverse (2018). In 2019, GMMTV formed the project girl group SIZZY, with Jan as its leader; the group also launched a clothing brand called Madly Dizzy. Her performance as the villain Tida in Who Are You (2020) won her the Zoom Dara Award for Best Actress in a Villain Role and earned a nomination for the 25th Asian Television Award for Best Supporting Actress. Over the next few years, she appeared in P.S. I Hate You, Cherry Magic, Hide & Sis, and Peaceful Property (2024). SIZZY signed with Riser Music in 2023 but disbanded on October 16, 2024 without releasing music under the label. In 2025, Jan starred as Lal in the series Enemies with Benefits alongside JingJing Yu.

Jan is known in the Thai entertainment industry for her versatility, moving between villainous and sympathetic roles with ease. Her Instagram feed, which has over 2.2 million followers, features selfies and modeling shots that cultivate a polished and accessible image. She is regarded as one of GMMTV's familiar faces, with a reputation for taking on challenging parts such as the antagonist Tida in Who Are You, which earned critical praise.

The collective following of Ploy Shompoo Supasap operates without a formal, singular designation in public records, though a specific collaborative identity emerged in mid-2026 when the mascot Jewel was introduced to represent the combined fanbase shared with actress JingJing Prariyapit. While her digital footprint spans 2.4 million followers on Instagram and nearly one million on TikTok, no organized campaigns, chart pushes, or distinct rituals have been documented for her individual audience beyond standard social media engagement. The absence of a named fandom does not diminish her reach, yet it marks a distinction from peers who maintain highly structured supporter networks. Regarding her standing in the global hierarchy of celebrity, iFANN has not yet collected sufficient data to assign a position within its ranking systems. Consequently, no ordinal placement can be claimed for her current fame level, nor can any movement up or down the charts be reported at this time. This status reflects the ongoing nature of data collection rather than a lack of professional activity. Her career remains anchored by significant roles in Thai television, including the antagonist Tida in Who Are You and leadership of the group SIZZY, but these achievements have not yet translated into a quantifiable global rank within the iFANN framework. The authority of the iFANN database relies on comprehensive signals that are currently being aggregated for this subject. Until those metrics stabilize and yield a definitive score, the record stands as unranked. This approach ensures that only verified, statistically robust placements appear in the final listings, maintaining the integrity of the global fame index.[edit]

Janhae is the portmanteau nickname combining her own name with that of Super Junior member Lee Donghae, a nod to her admiration for the idol. She holds a bachelor's degree in Philosophy, Politics, and Economics, an academic background that distinguishes her among her peers in the Thai entertainment industry. Prior to her solo acting career, she served as the leader of the project girl group SIZZY, which operated under Riser Music before disbanding; the group also managed a clothing brand named Madly Dizzy. Her entry into the public eye occurred in 2014 after winning a talent competition, a victory that led to a commercial appearance alongside Girls' Generation's Taeyeon. Although specific viral legends or crowd-disrupting incidents have not been formally documented in current records, her portrayal of the antagonist Tida in Who Are You remains a defining career moment noted for earning her critical acclaim and a Zoom Dara Award. A mascot named Jewel was introduced to represent the combined fanbase of Jan Ployshompoo and JingJing Prariyapit, suggesting a collaborative fan identity for their pairing.[edit]

Jan posted an Instagram photo with her mother in August 2017 for Mother's Day, but no further details about her parents or siblings are publicly known. She has not shared information about having any children or pets. [edit]
