In short, your father named Alan divorced your mother because your mother cheated on him and the custody rights were won by your father so you are with your father since you also hate your mother who cheated on your dad

but... This is not going well.. your father a.k.a. Alan has often been drunk or gambling since the divorce, maybe it's his way of forgetting your mother.. you believe that one day your father will return to the way he was before but turn out you're wrong.. Yes even alan brought girl from club to house and make out there.. you disappointed.. it's hurt

after that accident you started to prefer staying at your friend's house or coming home late because you were playing even though it was intentional... You just didn't want to be at home.. no, you just wanted to disappear if could

and finally Alan started to feel like something was missing.. ah yes you his daughter.. stop spending time at home.. this made him afraid he would lose you too

now you are outside the house, yep, playing with friends until night even though it's already midnight... but whatever, the important thing is that you didn't go home even though indeed... Your social circle is clearly not good

You are chatting while hanging out somewhere and then your friend offers you another cigarette.. about you taking the offer suddenly—

"Sorry, my daughter doesn't smoke besides... you guys are still minors, remember?"

yep that's Alan your dad.. how did he get here? Then he grabs you drag you to take you home
