CEO (Author)
BIOGRAPHY
CEO is the pen name of a Thai novelist, and the author of Until You #RiakDadSiThan (Thai: Until You #เรียกแด็ดสิธาร), the source novel behind the 2026 Thai boys’ love drama Your Dear Daddy.
The novel was first serialised in twelve chapters on the web fiction platform Tunwalai, then published as a single 633-page volume by Deep Publishing, an imprint of Satapornbooks, on 1 November 2021. Neither the Tunwalai listing nor the Mebmarket e-book page discloses a legal name; both credit the author only as CEO.
The adaptation, Your Dear Daddy (เรียกแด๊ดสิธาร), ran eight episodes from 9 May to 27 June 2026 on Channel 9 MCOT HD and iQIYI International, written and directed by Natid Kaveekornwong. A man exiled from his family finds his way to Chiang Rai, where a guarded local helps him recover and, in the process, teaches him how to love. Pusit Dittapisit plays Sila and Jitaboon Ngamboonyarak plays Saithan, both across all eight episodes.
Nothing beyond the pen name and the work is published anywhere. This profile records the pen name as the publisher printed it and asserts no identity beyond it.
BLGLFlix editorial view
Twelve chapters online became six hundred and thirty-three printed pages. That is worth pausing on, because it is how a large part of the Thai BL industry actually works. Web novels are serialised free, in short instalments, on platforms like Tunwalai; if a title finds an audience, a publisher acquires it, the author expands it, and it comes out as a physical book; and if it keeps performing, a production company options it. By the time a series reaches the screen the story has already been through two commercial filters that had nothing to do with television. When people ask why Thai BL adaptations so often feel like they arrive fully formed, this is the answer.
The adaptation moved it a long way from Bangkok. Your Dear Daddy is set in Chiang Rai, in the far north of the country, and it went out on Channel 9 MCOT HD, a terrestrial public broadcaster, alongside iQIYI International. That is an unusual combination for the genre on two counts at once: Thai BL is overwhelmingly a Bangkok-set, streaming-and-cable business, and a state-linked terrestrial channel carrying it is a different kind of placement from GMMTV’s or One31’s. The series also has a single person credited as both writer and director, which for an eight episode production suggests it was made as one person’s piece of work rather than assembled by a team.
A word about the pen name, since it is an unusual one. “CEO” is a common English noun, which makes this author very difficult to search for and effectively invisible in any database that indexes by name. We keep the profile title disambiguated for that reason. The absence of a legal name is not a gap in our research: it is what the publisher published, on both the platform and the e-book listing, and we treat that as the fact rather than as a puzzle to solve. Chasing the identity of an author who has chosen not to give one is not what a reference site is for.
One structural note for readers navigating the site. We hold the novel and the series as separate records, because they are separate works with different dates, different creators and different lengths. The novel is from 2021 and runs 633 pages. The series is from 2026 and runs eight episodes. Treating them as one entry would flatten five years and two different authorships into a single line.
