The Jester(1988)

Overview:

Taking advantage of his intellectual superiority, the teenager Valya Uspensky subtly and mercilessly takes revenge on others for small and big offenses. The young mathematics teacher Igor Aleksandrovich also falls into the field of his interests, whose intelligence and tact will properly influence the guy. But the young intellectual will suffer a crushing defeat in the seemingly ordinary everyday situation, which will be set up for him by his sweet, pretty classmate Ira - if only in order to once and for all teach the narcissistic jester a lesson.
