Reid Hayward had her heart shattered by Kylie Love. It's years later and she still can't let herself get close to anyone else. Then Kylie's sister, Sophie, moves into her apartment building, into the apartment right next to Reid's. Worse, Sophie looks so much like Kylie that Reid's initial response is openly hateful.
But slowly, over time, Reid realizes it's not fair to blame Sophie for what Kylie did. And as this realization happens, she begins to see Sophie for who she is, not who Kylie was. Once the ice is broken, Sophie, a newly out lesbian, asks Reid to teach her how to pickup women. And Reid, knowing this is the worst idea ever, agrees to it anyway.
The inevitable happens from there, with a few bumps along the way, but yes, it's a Chelsea Cameron HEA for sure.
