Both lakorns deal with the male leads wanting revenge against the female leads for causing a car accident with their loved ones. While Sathit's fiance passes away in Kleun Cheewit, the male lead's sister in Ubat Rai Ubat Rak becomes handicapped. Coincidentally, the supporting actor (Masu) who plays Jett in Kleun Cheewit also happens to be the male lead in Ubat Rai Ubat Rak.
