Teach Me to Love (2008)

Mark is a high school senior who makes a personal problem out of his parents break-up when his mother leaves home for another woman. The thought of being the butt of jokes for "having two fathers" horrifies him. All these worries and angst take the backseat when a new teacher comes to campus. Her name is Connie and she is an instant hit among the boys. It is love at first sight for Mark. However, Connie has an affair with Vincent, a married man.
