The Lost Soul Season 1 Episode 17

Taechyd is a police officer who was ordered to go into hiding by his superior after his case with a drug dealer fell apart when the evidence against the criminal disappeared. Techit goes and lives at a resort run by Sritrang, his childhood friend. They both wanted to become cops ever since they were young. Both of them made it, but Sritrung had to quit after both her parents died in an accident and she ends up having to take care of the corn farm and resort. Eventually, Taechyd meets Siangwaan (Min) a ghost who doesn't remember anything and knows nothing. I guess he calls her Siangwaan because of the sound of her voice, sieng waan means "a cheerful voice." Taechyd must figure out why Siangwaan is haunting Sritrung's resort and why he is the only one that can communicate with her. On the other hand we have Paul, whom Sritrung and Taechyd believe to be the right hand man of the bad drug dealer. He has a history with Sritrung. He was her elder in college and they dated for awhile before he had to leave Sritrung. They must work out their feelings for each other while trying to figure out the mystery of Siangwaan.
