A Muse (2012)

Lee Jeok-yo is a 70ish year old man who is a respected poet. He cares fondly for his 30ish year old disciple Seo Ji-woo. The world of these two men are shaken when 17-year-old high school student Han Eun-gyo comes into the picture, as their mind and sexual desires are awakened.—Stanislav S, Sochi, Russia
