Mandatory 7 Days

Marek is your typical, run-of-the-mill guy – a middle-aged, heterosexual white man, divorced, a workaholic, and a lover of routine. So it comes as a genuine surprise when, without any warning, Riki, an emotionally unstable bubble of a person and, above all, his former brother-in-law, moves into his house.
Looking after this bratty teenager for a week shouldn't be a problem for Marek, if only the first thing he heard wasn't: “I love you, I want to live with you as your partner.”
This kicks off a merry-go-round of romantic advances and loving confessions from Riki, and rejections from Marek.
Is it true that love doesn't choose?
