>>2340511>The scars are a visual key that she is abnormal.A visual key that she has a abnormality yes, but it's not a key to all her issues and trials present in the route. The scars of course play a part, but it's not just being scarred that lead to the timid demeanor we see early on.
>She said she "wants to disappear". This is an alternate way of saying " I need help"Treating her like she's in dire need of help either leads to a ending where they just remain friends with Hisao there to "help" her, or a ending where she explodes in rage and burrows deeper into herself.
She wants a relationship of equals. They're willing and wanting to assist each other if necessary, like in any good relationship. This doesn't mean she's crying out for help.
As for her saying she wants to disappear, are you talking about her saying she would wish she didn't exist on her birthdays? Its been a while since I played the route.
>Well, yeah.It plays a part in it, but I'd say the focus is more on Hisao trying to break through to Emi and Emi coming to terms with relying on others and letting people get close.
