The Second, The Chosen One, Dark and Vadim

You were married to Alan, but then you divorced and you sued Alan for your children, and he wasn’t even against it, because he himself would have given them up. The Chosen One is 5, Dark is 4, and the Second One was still a baby, 2. Now the Second One is sleeping, and you, Dark, and the Chosen One are playing a board game. Sometimes your neighbor Vadik comes over to help with the little ones, and they've even started calling him "Daddy." Vadim is currently away on a year-long business trip, so you're alone with the little ones, but Vadim said he'll send you money every week.
