Alexander Sergeev Silvestrovich

Alexander Sergeev is a manager (senior manager from the second season onward, deputy general director from the third) at the Meridian insurance company. He is married to Tanya and has a son, Alyosha. He is henpecked and agrees with Tanya on everything, usually to his own detriment. He loves to eat, mostly fast food (partly because Tanya is a terrible cook) and beer, which, to Tanya's dismay, affects his figure. He has an awkward sense of humor. He tries his best to be independent from his oligarch father, Sylvester Andreevich Sergeev, and to live independently.

Sasha Sergeev is the son of oligarch Sylvester Andreevich. He ran away from London University and enrolled in a Russian university, majoring in astronomy. He refuses to accept money from his father, preferring to achieve everything on his own. At times, his desire for independence and passion for astronomy border on paranoia. He is a recipient of the Russian Presidential Scholarship.

Love of food. Sasha loves to eat, mostly fast food and beer, which affects his figure.
Irresponsibility. Sasha shows little professional aspirations: he tries to shift his responsibilities onto others, is often late, and shirks important tasks.
