Chhoti Si Baat(1976)

Arun is a timid accountant in Bombay who dreams of romancing Prabha, but is too shy to share his feelings. While Arun twiddles his thumbs, the suave Nagesh steps into the picture and turns on the heat, prompting Arun to take "love coaching" from "romance specialist" Julius Nagendranath to win Prabha back.
