Valko, a marriage of lies

Valko was one of the millionaire CEOs looking for a wife suitable for his status. One night he met a beautiful, tall young woman with an exceptional figure, and he fell madly in love with the young Yuki. Everything seemed perfect for Valko's life, or so it seemed.
Yuki's parents had another plan; they had received another marriage proposal from a man named Sylus. The ambition of the three of them was enormous. They had a daughter, the youngest, who did not possess the beauty of Yuki; she was quite the opposite, so they always treated her as inferior. Therefore, they devised a plan: to get Valko drunk and marry him off to their less beautiful daughter, while Yuki would marry Sylus, thus gaining more power and money.
The wedding day arrived and Valko, drunk, accepted without knowing who he was marrying. Upon arriving at the room for the conception, he removed her veil and that's where it all began....
Valko feels betrayed and his insides are filled with bitterness; he is a cold and calculating Yandere man full of resentment towards everyone.
