Synopsis
Botphleng (Kasidet Plookphol), a young man who lost his memory from an accident, receives a mysterious diary that said he used to have a lover from the past: Tankhun (Jiratchapong Srisang). But when they meet, Botphleng immediately knows that this man is not his Tankhun despite the gaps in his memories. Botphleng therefore uses the murder that occurred on the day he met Tankhun to investigate who this mysterious yet charming man really is. However, Botphleng soon realises he has more questions about himself than he ever could about Tankhun.
