But what if she's there just to provide an idea of the life Hisao had before his heart problem arose? She's there to show what Hisao has lost.
Actually, I think she'll be used for the opposite. I don't think she'll show up again, but I do think she'll be mentionned when Hisao tells his girlfriend the details of how he ended up at Yamaku. It'd contrast his crush on a girl who was basically a complete stranger to his feelings towards, say, Shizune at the end of Act 1.
