Predannyy Drug (2008)

Years ago, Igor and Misha were inseparable friends, sharing everything, including a love for the same girl. They met Inna in college. Beautiful and vivacious, she was always surrounded by suitors. Their close friendship subtly evolved into a love triangle; both men were in love with Inna, who couldn't decide between them. Jealousy threatened their bond, so they made a pact: to sacrifice their love for friendship and never see Inna again. Their youthful ideals couldn't hold. After college, Inna never managed to break through, Misha disappeared mysteriously, and Igor, securing a good job, moved to another country without ever seeing his friend again. It wasn't until years later that life rearranged everything.
