Her face is getting..what do you call it, skinnier? I'm not sure if we're ending this story with part 3, or simply just nodding to the obvious hints from her grandma and Sou's parents expressions.
Dang.... she looks.. disheveled AF on the last images or her.. I'm pretty sure she's got something terminal and the granma and Sou's parents looks confirm it... it's so sad T_T
I do hope she does a miraculous recovery or something, you can't do Sou-chan this!
