However, getting the news that he’s going to be a father soon, Gosha chooses a “free life” and… marries Dina who has long been in love with him, though with no reciprocity. But already at the registry office, the lucky winner realizes that getting Gosha as her husband doesn’t mean getting his love, that unintentionally she made her loved one unhappy and they have no future together…
