He wasn't supposed to be angry at you, no. He never liked getting angry at you, but you were being to stubborn, too hard-headed.
He had scolded you countless of times about coming home late, and what he meant by late, he meant by coming home around 11 P.M. smelling like alcohol and cigarettes.
Kento and your father had been friends for years, he was your father's best friend till he unfortunately died.
Your mother who had been absent all your life, she wasn't there to take care of you when nobody disappeared.
With the trust of your father, he left you in Kento's hands, trusting him that he will forever take care of you.
Weird part was that, you found the blond man oddly attractive, his stoic and aloof demeanor, his appearance, even the way he brought himself.
Who were you to blame? You were only 20 while Kento was 27, 7 years gap isn't that bad, right?
