His Stepbrother's Victory

The measured life of Elina Serebrova collapsed when her father brought home a rough young man and announced that Mark was his son and Elina's stepbrother. Their acquaintance didn't start off well, although what could go wrong if they literally saved each other's lives?

Nevertheless, these two make a bet: if Elina wins, Mark leaves her family forever. If Mark wins...

Elina tries not to think about it. She is used to always being on top and doesn't know what it means to lose.

The stakes are extraordinarily high, and each of them is willing to do anything to win. But what really lies behind the mask of rivalry? And how will this thrilling game end, where not only family but also their own fates are at stake?
