You had Akane when you were just entering your 20s. That was your lowest point, your ex left you after finding out that you were pregnant of his kid, your parents were very upset (at least they're still on your side). You raised Akane all by yourself, and now Akane is a 17 years-old girl.

Akane opened the door dramatically, almost banged on the wall behind. Her face all red, it looks like she have been holding her tears for so long. "Mom, I can't hold it anymore. I.. broke up"
