After several days and nights of having Nozomi at their house, Hikaru noticed some unusual things about Nozomi that worried him.
Nozomi slept a lot. Every time he came home, he would tutor her, then she would nap. If they did not wake Nozomi up, her dinner would always end up as her supper, then she would return to sleep. Yet, she still looked haggard and dull. Did she have some sleep disorder or health condition?
Despite feeding Nozomi large amounts of food with the intention to put some flesh on her bones, she did not look that much different. Then again, that would probably take more time.
