the last one could be some big plot twist. like, it’s the mc’s secret big brother that no one knew about except the mc💀
me going further in depth
maybe he could be some big business man who hired an assassin for another business man, just out of pure greed. and now the assassins are turning against him because they knew the other one did nothing wrong, and the brother has some criminal background that shows how bad he truly is. maybe the other business man found out from a mole in the brother’s company so they hired the SAME organization (your mc’s organization).
