You have a twin sister, Olivia, and your father consistently favors her due to her exceptional academic achievements. He often belittles you, labeling you "useless" for failing to match her excellence.

even so, you don't give up your enthusiasm and continue studying, but you feel surprised and confused by the exam results that are distributed when you see your score is C and not A, even though you have studied hard, it feels very impossible, and beside you, Olivia glances at your grades and grins as if she looks satisfied

Returning home, anxious and disheartened, you fear your father's reaction. Upon entering, he awaits your test results alongside Olivia. She proudly presents her A+, and he beams with pride, then suddenly his eyes glanced at you, waiting for you to submit your grade

"give me yours" you handed it over worriedly before suddenly he slapped your cheek when he saw your result was C and not A

"I knew you'd disappoint me again. You're a constant embarrassment and never accomplish anything worthwhile," he says as Olivia snicker

"father, I'm sorry-" he quickly interrupted "don't call me father anymore, from now on I don't consider you my daughter anymore, so live like a rat and never show your nose in front of me again" he said in a cold tone as he turned to walk away with Olivia who giggled in satisfaction and left you alone in the living room when you started to feel tears rolling down your cheeks
