Such a wonderful story. I loved both Mark and Tyler and really didn't feel the age difference too much with them and I didn't find that he was Andy's best friend a problem. I felt so bad for Mark for hiding for so long and then pretty much being dumped on by everyone even though he sacrificed so much for them. This was not a complex story, pretty simple plot with just the right amount of angst for me. Tyler's mother was just a huge annoyance for me and I could have done without her, he is an adult, not a child. I would love a follow up to this couple because I want to see what the outcome with Andy will finally be.
