BIOGRAPHY

Prachaya Ruangroj (Thai: ปราชญา เรืองโรจน์; born 28 July 1994 in Bangkok), known as Singto (สิงโต), is a Thai actor. He is best known as Kongphop Suttilak, nicknamed Kong, the engineering freshman who stands up to his senior in SOTUS: The Series.

His GMMTV contract ended in April 2021 and he returned to the company in 2024. The list begins with SOTUS in 2016, followed by SOTUS S in 2017, then Friend Zone in 2018 and 2019 as Earth and He’s Coming to Me in 2019 as Med. I’m Tee, Me Too in 2020 gave him Maitee, and Turn Left Turn Right came the same year. He appeared in Baker Boys and Paint with Love in 2021, Shadow in 2023 and Tamtawan in The Ex-Morning in 2025.

Opposite him in SOTUS is Krist Perawat Sangpotirat as the senior Arthit. The series premiered on 20 August 2016 on One31 and LINE TV, and its sequel SOTUS S premiered on 9 December 2017 with both leads returning.

The pairing with Krist Perawat Sangpotirat frames both ends of his list: SOTUS and SOTUS S at the start, The Ex-Morning in 2025 near the end. In between, each credit is a different named part: Earth in Friend Zone across 2018 and 2019, Med in He’s Coming to Me in 2019, Maitee in I’m Tee, Me Too in 2020, then Turn Left Turn Right in 2020, Baker Boys and Paint with Love in 2021 and Shadow in 2023.

Kongphop’s setting, an engineering faculty with a hazing system, is described on the SOTUS page, which also lists Thitipoom Techaapaikhun, Neen Suwanamas and others in the cast. A viewer who wants to follow Singto’s career can read that page first and return here for the rest of the list.

The company line is worth reading with the list: his GMMTV contract ended in April 2021, the same year as Baker Boys and Paint with Love, and the return in 2024 comes after Shadow in 2023.

Reviewed by Renkaze, editor of BL & GL Flix

Singto’s list has ten entries, and the most useful detail is the break in it. His GMMTV contract ended in April 2021 and the list carries on with Shadow in 2023, so the credits do not stop when the contract does.

What I notice is that his first two entries are the same story, Kongphop in SOTUS and then SOTUS S, and the roles after it are all named characters with their own series: Earth, Med, Maitee, Tamtawan. The Ex-Morning in 2025 is also on Krist’s list, so the pair are credited together again nine years after the first series.

If you are new to him, I would start with SOTUS: The Series, watch SOTUS S, and then try I’m Tee, Me Too to see a role from 2020.
