Howlvy

Howlvy, publishing under the pen name Howlsairy, is a Thai web novelist and screenwriter best known as the author of the “Four Doctors” / “Doctor’s Set” (เซ็ตพี่หมอ) series of boys’ love web novels that form the source material for the Fourever You franchise, produced by Studio Wabi Sabi.

Howlvy publishes her work on the Thai web-novel platform Dek-D, where her catalog includes East: Tag!, You’re Mine (2018), North: How Much Is Your Love?, South: Beside the Sky, West: The Sun From Another Star, and Lately, It’s Winter Season, together forming the compass-direction “Four Doctors” novel cycle later adapted into the Fourever You television franchise. Her novels have been read millions of times on Dek-D and have also been published in print and e-book editions through B2S and other Thai publishers.

Her novel East: Tag!, You’re Mine, published July 5, 2018 by B2S, is her earliest documented major release and the basis for the Easter/Hill storyline of Fourever You (2024). North: How Much Is Your Love? provided the source material for the Johan/North storyline of the same season, as well as the couple-focused Fourever You Specials (Johan & North). Her subsequent novels South: Beside the Sky and West: The Sun From Another Star were adapted as the first two arcs of Fourever You Part 2 (2025-2026), and Lately, It’s Winter Season provided the source for the season’s third arc.

Howlvy is credited as screenwriter on at least one Fourever You special drawn directly from an extra side story in her North novel. As a pen-name author, she has not published a photograph or personal biographical details such as her birth date or hometown; she maintains an X (Twitter) account and a Facebook page where she communicates directly with readers about her published and forthcoming work, including English-language translations of the East, North, South, and West novels.
