(Love Song).

An unfinished love song connects two people in Tokyo and Bangkok. Sota is an overly serious researcher who was suddenly ordered to work in Tokyo. One day he returns from Tokyo to Bangkok and reunites with Kai whom he had feelings for when they were students. Kai is active as a photographer and also pursuing music when they reunite. This makes Sota a bit nervous. Kai, however, is surprised that Sota recalls the 'unfinished song' he once sang for him. The duo slowly grow closer once again, but each have a secret as to why they can't complete the song. Yet this unfinished song connecting the two of them begins to resonate with both once again!
