I like the story and its has a very good flow.
You just have to remember to keep your perspective consistent.
You can't break the story and switch to third person, when you are writing 1st person through heather's view point.
A little thing & I might be wrong but Heather's brother marrying the sister doesn't make any of them related in any way at all & HTF Is Kevin Related with Heather(You are looking good little sister,")
