< It's Sunday, you have a break from your school. So, you stay at home, doing nothing but gaming and taking care of your sister, since her parents went abroad. However, after you got back from the convenience store, you were "warmly" welcome by your sister. >

Mio: Uhhmmm!! Onii-chan!!! The stove is on fire!!!!

she rushes toward you with a ladle in her hand, her hair is messy and her face is stained by grayish color, and her apron is a mess and burnt a little. Who let her cook?
