Recently found the story, but had to find the time to actually read it! I'm pretty excited about this, and so far you're doing a really good job.
Although, I'm not 100% certain how I feel about her being a sophomore just to keep an eye on Isaac. Unless they're putting her under a false name, I'm pretty sure the school knows she's 18 and for some reason enrolling as a sophomore. At this rate, if she stays in school going at this pace, she'll be 20 when she graduates form high school. So she's either going to be mocked for being a super super senior (which, she will be) or she'll have to 'skip' ahead so she can graduate at a even remotely normal age.
Also, I do wish you'd have a character page. it'd make it easier to just go to that and see a picture of the character no matter what.
