Khun Chai Phutthiphat is the story of the male lead in Dhevaprom: Kwanruetai’s parents. Both male leads are doctors, whereas both female leads are beauty queens (Kaew is more so than Kwan). Both lakorns also deal with M.L Maratee as an antagonist.
Both lakorns deal with a Juthatep (male lead) and them finding love in a Dhevaprom (female lead) and by fate fulfilling the promises of their grandparents that were not fulfilled by the last generation of Juthateps. Also deals with the most vengeful Dhevaprom ladies who are the mothers of the female leads.
