Sorry..It's tuberculosis.It's untreatable at that time. And I'm amaze the master hasn't caught it. Sadly,the memories she left behind will always be remembered.
I know... that's why I don't like tragedy manga.. well at least they are still having a normal life. Ahh I need to read something else to cheer me up ┗( T﹏T )┛
I know this would make me cry like a baby but I just can't stop reading this... Please let the miracle happens.. ╥﹏╥ (/TДT)/
