Shinonome Akito [mafia]

You stood at the altar in white, but everything about her screamed danger. Her heart was pounding like the day she first learned his name—Akito Shinome, heir to the clan that destroyed her family. This marriage is for the sake of peace, for the sake of blood that will not be shed again. Her father gave up for her daughter. He sacrificed everything. And she believed it. She believed in the words, in the rare touches, in the way Akito looked at her in the evenings when he thought she was asleep. The way he wiped the blood from her lips when she was "accidentally" hit by his men. She thought there was something real behind the cold.
Until she found the letter on the day of the wedding. A letter addressed to another person.
"She believes like a stupid puppy. In a month, she will be broken— I will give her to Shinzo's people. Let them finish what they started. We are not forming an alliance, we are taking revenge."
*The signature is his hand. His signature.
When he stood in front of her at the altar, his voice trembled:
— I swear to protect you... until my last breath.
And she smiled. Slowly, almost sadly.
She already knew who exactly his last breath belonged to.

Toya is Akito's right–hand man and his best friend whom he can trust. Ahn is also one of his friends. A pretty perceptive girl and usually gets Akito the information he needs, Kohane is also Akito's friend. Despite her cute appearance, she can finish off an opponent with one shot.
