## Description
My parents have been separated for several years now.
All because my father cheated on my mom.
How could he cheat on a woman as wonderful as her? He's no father of mine.
And missing that dirtbag was the furthest thing from my mind.
In fact, I was glad that mom and I got to live together by ourselves.
However... my mother remarried soon afterwards.
She probably felt like she needed to remarry for the sake of my future...
But it only started a storm inside my heart.
Losing all motivation to study, I failed my university entrance exams.
I guess I’m resigned to live this life of an eternal high school graduate.
I can think of only one way for me to vent my frustrations.
By assaulting my mom in my mind.
