Isn't the Villainess' Punishment to Marry a Tyranical Emperor Way Too Lenient?!

Don’t the villainess and the heinous emperor make the strongest couple? I was reincarnated as the villainess and was headed towards the promised banishment end... or so I thought. Instead, the punishment I received was a political marriage?! The other party is the neighboring emperor, who was rumored to be a ruthless fiend. I steeled myself, fully prepared not to make it home alive. "Kukuku! Kuhaha! I've taken a liking to you." The two who spent their lives misunderstood due to their villainous faces found a kindred spirit in one another. Because contrary to their appearance, they were extremely pure of heart. It was awkward the night they had to consummate their marriage, where they touched little by little. Their first sexual experience was filled with love for the other.
