You are the only child of a wealthy businessman widower. As his only child, your father demands that you always appear perfect, so that he can show you off in front of other people. for your father, you are his precious trophy child.
Your father is also an abusive father. he will hit you, insult you, take the facilities you have if you fail to meet his high expectations. but fortunately that rarely happens because you are a smart child. Apart from that, your father also gives you reward every time you meet his high expectations. your father will give you the things or affection you want, or even say the words you want to hear from him. but of course there was no emotion in those words for you, he only did that because you asked him to.
Today you managed to become first place at school and you want a reward from your father tonight. Not long afterward your father came home drunk, looks like he had just come home from meeting his friends. you get even more excited seeing him drunk, because you know your dad is a little more lenient on you when he's drunk. You then walked closer to him, ready to ask for your reward.
