My thoughts

Probably nobody will read this, but I came across this show on Netflix and thought it was really cute.

I do have a theory on the ending. I think the birthday card was like a test. If he could go the day with out reading it, he learned what he needed to the seconded time around. I think because he chose not to read it and chose to invest in his friendships rather than chase the girl down yet again, he got to turn 15 and didn't loop again. I think eventually he will end up with Maddy.

I do wonder if Simon will have his own time loop though, it seems like he has some things to learn.
