It's a enjoyable story but i didn't like the end that much. The characters are both nice. I understand why some people find it weird with her being 13 only. I kind of wish the Teacher was younger around 22 or 23 and have the student be around 16 or so. The ending bugs me with how they leave it with the mom. I get that the daughter isn't happy with the mom but i don't like how they left her in what looks to be despair. It's honestly really unintentionally sad and depressing. The daughter even mentioned not wanting to leave on badterms with her parents but yet they end the story like that.

I thought the story would be something like the mother allowing her to visit the teacher every now and then and have both the MC's on somewhat good terms with the mother. Hell , The mother must care somewhat sense she even wanted her daughter back in the first place.

Otherwise it's a pretty interest and fun story.
