Good luck, Nana
According to the doctor, without the surgery she will get worse and die. By operating she will at least have a chance. She will be operated today. She's a strong girl, but surgery will stress her and take lots of her strength.
I will call Dr. Ozawa later and ask about her condition. If I can leave work early I will go tonight to see her. If I can't, I will go tomorrow morning.
Update: I called just now to ask about her condition. The nurse who took the phone told me that Nana has been operated already and she's sleeping now, but that she doesn't know much else about here condition. I will go to the clinic later if I can leave work early.
