OMG, there are still/again people complaining about the age? You should have dropped this at the beginning then when the girl was still 12.
And so far sensei hasn't done anything, it's all been the girl chasing the teacher.
Oh my, what a roller-coaster of emotions - first the despair, now a high, and soon back to despair. But I hope it won't be as bad, now that she knows someone she can talk to.
