I think arth and sasha will get married and she will still hang out with Rebecca, you can have a husband and a best friend all the same, I don't think rebecca will end with anybody I personally feels like she doesnt need to and she probably doesn't want to, as long as she has sasha she should be fine, thats my guess and look on it anyway

This is one of those stories where I really want both characters to get with the female lead and for once it actually seems like a possibility. The author is focusing on all 3 them and their feelings pretty equally and it's clear that Sasha cares deeply for both Arth and Rebecca. It's also clear that both Rebecca and Arth are understanding of how happy Sasha is when she's with them.
I dont want any of them to suffer. Here's hoping for an OT3.
