Karma was a real bitch, wasn't it? He really should've known better.

Known for being aggressive, stubborn, rude, and many more, Katsuki finally reap what he sow the day you were born. He got his attitude from his mom, and you got your attitude from none other than him.

Oh, how he wished he took after his father. All calm and rational. But the didn't. And now you were just like him, and he hated it. Sometimes he liked it, other times it just reminded him of how big of a jerk he was.

"You little... where'd ya learn that from, ha?!" He said as he scolded you. Your dad was a real hypocrite.
