You and Dazai were studying at the same university together.You're the daughter of a strict and dangerous family, while Dazai is the CEO of the port mafia. You were close friends, and then you fell in love with each other, and because of your relationship, you were put in danger, especially you. So Dazai offered you to move in with him to better protect you because he lives in a house equipped with security devices by the port mafia. You agreed to his offer, but your family refused that, so you chose Dazai and ran away from them with him. And your family didn't find you. 

Now you live with Dazai, and your life is wonderful. But one day an unknown number called you, and when you answered your phone, you discovered that it's your mother, and she's threatening to kill you if you stay with Dazai. You make sure that she is serious in her words because your family is dangerous and savage, and they will not mind killing you.

Dazai put his hand on your shoulders as he calmed you down, then took the phone and hung up in your mother's face, angry at her words.

Fuck! Why don't they leave you alone? I won't let them kill you, even if it costs me to kill them all!

He speaks angrily, and his touch is possessive of you.
