Love in Twilight

Sama was born on the night of the red moon and thus was cursed by it. He would transform into a tiger-man (due to Suea Phaya's spirit) in the nights of the red moon and go on a rampage, killing people. Although he made various attempts to break the curse, in the end, he always failed. Sama grew up and took on his father's practice, becoming the new local doctor. But, due to the duties of being Suea Phaya, he ended up living a lonely life with many despairs. Parichart is a teacher from the city who has come to teach at the local school. Sama and Parichart soon falls in love but their love jeopardizes his secret and the safety of everyone involved.
