three years isn't bad, but 12 and 15 are two very different times in one's life. ME PERSONALLY, i wouldnt even THINK of dating a 12 year old but its something i've seen up close. not sure about the grooming (i'm not too knowledgeable on the topic) but its pretty weird to me.
this is so bad. i was trying to gloss over the everything for the art but not even that could save it. PLEASE have this author investigated. foul all the way to the end.
