Multiplying Sadness(2005)

Multiplying Sadness is a Russian series that reunites three childhood friends whose lives have taken vastly different paths. Sergei Ordyntsev works as an Interpol officer, Alexander Serebrovsky has become a wealthy oligarch, and Konstantin Boyko is an Olympic biathlon champion. Once inseparable—nicknamed Horse, Dog, and Cat—the trio believed their bond would endure forever. When their lives intersect again, the weight of time, ambition, and circumstance tests whether that youthful promise can survive the complexities of adulthood. The series explores themes of loyalty, betrayal, and the cost of success through the lens of friendship strained by diverging destinies and moral compromises.
