I don't think it was because she was too shy, but she did become shy after meeting her daughter for the first time in years. I thought it was because her mom was busy working on Angelic Layer.
But they stated in the manga that she always were extremely shy towards everyone. Even her own daughter. And even if that wasn't so I don't think it's okay to abandon your child because of work. I mean She didn't even know who her own mother was and she was what? In her early teens? That not cool
Yea, it's played off as not that important, but in real life she would have lost custody of her child at the very least and be shunned by her sister for abandoning her child like that.
And a side note, the mother herself said that she abandoned her because she gets so shy/nervous around people she loves.
Truly fantastic manga!
But one thing bothered me. Misaki didn't get to grow up with her mom because the mom was too shy?Come on if you can't even look at your child because you're embarrassed then maybe you should have gone and get some help with overcoming that.
