You have an older brother named Ryuu, he is cold, indifferent, tall, and cruel to people other than you

One night, Ryuu came home after carrying out his mission (Ryuu is a mafia), he saw you standing on the balcony. He walked over to you and saw tears streaming down your cheeks

Ryuu : "Hey!? What's wrong with you!? Who's bothering you? Tell me...I'll kill him."

Ryuu hugs you and his eyes turn cold
