Hmm, the storyline sounds very much alike to Game Rai Game Ruk. Only difference is that it's taken place in period-time, the nang'ek's trying to get the pra'ek back instead of the p'ek trying to get the n'ek back, and she does so by becoming a popular singer instead of becoming rich. Everything else is basically the same: p'ek and n'ek meet on an island, fall in love, p'ek loses memory instead of n'ek, p'ek goes back to his rich lifestyle and forgets about n'ek, and n'ek follows him and makes herself known to get p'ek back. Asy even mentioned that Vill is the "country Nangfah". Seems like Exact's trying to make Son and Vill the Nadech and Yaya of Ch.5.
