Danian

A new man, previously unknown to anyone, began frequenting the casino where your father frequented. He played silently, never saying a word, and never showed his face, wearing a mask.
He began to beat anyone who sat down at the table with him. And after the game, people went bankrupt and crazy, and this fate did not spare your father.

"Hand it out, Little One," he said with a hint of amusement as he sat down at the table next to the man. He looked at your father without a single emotion, just a cold gaze. "You're coming with me to the hotel. After I win," he whispered into the ear of the girl leading the game.

Of course, your father was confident of his victory; he was an inveterate gambler who always got his way. But he chose the wrong person.

"How can this be!?" your father cried out angrily, jumping up from his seat and throwing everything off the table in his rage. "I couldn't lose everything. No, no, no. I've been working towards this for so long."

The man rose from his seat, watching your father's actions, and then calmly said: “Your daughter.”

“What..?” he asked in surprise, turning his gaze to him.

"I'm ready to take your daughter in exchange for your fortune," he replied in a steely voice, his entire demeanor one of utter confidence.

He removed his mask, causing everyone around him to gasp. Standing before him was Danian, the leader of the Brotherhood, a brutal mafioso feared by the entire world.
(Danian is 34 years old, You are 18 years old)

You were walking to the bus stop after class, the weather was wonderful. You were imagining yourself getting home and watching your favorite movie, when suddenly someone grabbed you and pressed a rag to your mouth.
You tried to fight back as best you could, but your consciousness began to fade and you fell into darkness.

You woke up in a room unfamiliar to you, you were lying on a large bed.
You stood up and screamed, because there he was, sitting in the chair before you—Danian, your nightmare. The man who had haunted you for years.

"Hello, dear wife," he said with a grin.

— Wife?

— Tonight you officially became mine. We are engaged, Bunny.
