Bexan's mum is the white haired werewolf, and his dad is the white haired werewolf that Mum shot in the flashback. Mum fell in love with a human lady (the performer and the black haired lady in Bexan's flashbacks). Mum didn't love Dad (cuz he was abusive or something, I don't remember) so when she found out she was pregnant, she ran away with black-hair Mum. Bexan was born and stayed with black-haired Mum, while actual Mum went back to Siberia (or where ever) to tie up loose ends and "keep Bexan safe" etc.
I missed a tonne of details, but whatevs. Hope this helps

Correction: Bexan's dad is the black haired wolf. In his wolf form he's a black wolf.His name is Pei.
The dad is very possessive up to the point killing half of Milena's ,Bexan's mother, family to get what he wants.
When the mother felt she was pregnant by him she went to the human named Iho, Bexan's adopted mother, to ask for help worrying if the dad ever finds out that she's pregnant he would become more insane.
And she's afraid she'll loose Iho too, the human that she loves.
So long the baby doesn't see the sun, she won't change into a wolf taking this opportunity to run away with Iho so Pei wouldn't find out.
After Bexan is born she left Bexan in Iho's care to take care of Pei and the other brothers. Before they hunt them down.

*The dad is black not white: http://www.mangago.zone/read-manga/wolf_in_the_house/nmt/c069/6/
