Teacher's Diary (2014 Thai Film)
Teacher's Diary, released in Thai as คิดถึงวิทยา (Kid Teung Wittaya), is a 2014 Thai romantic drama film directed by Nithiwat Tharathorn and distributed by GTH. The film explores themes of isolation, education, and long-distance connection through a shared notebook left behind in a remote floating school.

Production and Background
The film was directed by Nithiwat Tharathorn, who co-wrote the script alongside Thodsapol Thiptinkorn, Suparuek Ningsanon, and Sopana Chaoviwatkol. Production was managed by Jira Maligool, Chenchonnanee Soonthonsaratul, Suwimol Techasupinan, and Wanruedee Pongsittisak, with cinematography by Naruepol Chokanapitak. The runtime is 110 minutes.
The floating school featured in the story is inspired by a real institution known as Bann Ko Jatson School (Floating Classroom Branch), located in the Li District of Lamphun Province in northern Thailand. However, production did not film at the actual location; instead, the crew constructed floating school sets at Kaeng Krachan National Park in Phetchaburi Province.
Plot
In 2012, Song, a former wrestler turned teacher, begins working at a remote rural school that serves only four students and one teacher. To cope with his isolation, he reads a diary left behind by the former teacher, Ann. Through her entries, Song learns about her experiences and develops deep feelings for her, forming an emotional bond across time.
In 2013, Ann returns to the school and discovers Song's written entries added to her journal. Although he is no longer there, his presence transforms her experience of the isolated school, leaving her surrounded by memories of someone she has never physically met.
