So hungry

I am in KGU library to do my homework. I got up at 8 o'clock and came here at 10 o'clock. Now it's 18:23 p.m. I am so sleepy and hungry. I want to go back home but my homework doesn't finish. I will stay there at 21 o'clock. But I don't know whether I can finish my homework or not.
By the way, my sister, Urara caught cold. It is Influenza. She must do entrance exam in next week but she caught cold so she will do in other room. She always studied so harder so I want her to pass that exam.
