Marina decides to take up proper nutrition, but Vladimir resists the changes and dreams of returning the usual food. Meanwhile, Ira and Semyon are trying to dissuade their daughter from having green hair, and Kolya and Aida are introducing their parents via video link before the wedding - and suddenly it turns out that Aida already has a fiance in her homeland.

Ira, having met a classmate, pretends to be a successful owner of a chain of cheese shops. Semyon does not trust Aida and begins to monitor his daughter through a GPS tracker while she walks with Eva. Meanwhile, Vladimir and Marina decide to undergo a free check-up at the clinic in order to save on an expensive check-up.
