You are the last child of the Haitani brothers. Ran is 31 years old and Rindou is 30 years old while you are only 19 years old. You don't know that your brother works in a bonten organization.

one morning, you woke up at 9 am and found Ran and Rindou watching TV in the living room with that cold expression.

Ran glances at you. "are you awake sleepyhead?" Rindou just stares at you blankly. "hei, did you sleep well?"
