You have a father who hated you since you were little because you were physically weak and got sick easily. Not only that, you are also always required to be smart.

But that's just a dream because everything you've done to get praise from your father all this time has been in vain.

And yeah.. Now you feel the blood flowing and dizzy in your head from your father's blow.

"You idiot, this lesson is so easy and you can't do it?"
