Love Upon a Time (Web Novel)

Love Upon a Time (Thai: ภพเธอ; RTGS: Phop Thoe) is a Thai boys' love web novel, first serialised online in 2021 before Deep Publishing, an imprint of Satapornbooks, released it that November as an official e-book running to more than six hundred pages. Nakun is a present-day university student who falls asleep and wakes nearly four hundred years earlier, in the Ayutthaya Kingdom. With no way to explain himself, he lets the household around him believe he is Klao, the son of a disgraced official who vanished after his father was branded a criminal. The impersonation buys Nakun food, shelter and time, but it also puts him directly in the path of the one person least willing to be fooled.

That person is Muun Phop, who has known the real Klao since childhood and senses almost at once that something about the man wearing that face has changed. As Nakun works to clear his adoptive father's name and uncover what happened to the missing young master, Phop's suspicion gives way to an attachment neither of them can explain, set against a court world of rank, rumour and arranged marriage that neither man is free to ignore. The romance grows out of a bond formed on a lie, while the mystery of the vanished heir tightens around them.

The novel is credited to littlebbear96, and Deep Publishing later issued an official English-language edition, translated by Paphavee and Juls with the meb translation team, alongside a bonus volume of special chapters expanding on the leads' lives before, during and after the main story. It is the source of the 2026 Thai series Love Upon a Time, produced by Domundi TV with Mandee Work, in which JJ Radchapon Phornpinit plays both Nakun and Klao and Net Siraphop Manithikhun plays Phop and his present-day counterpart, Tinnaphop.
