All Mine

Alternate ending book to Secretly His.

After ending her two year relationship with Chris Evans and breaking off their engagement, Cas Hemsworth found herself falling for their mutual friend Sebastian Stan. Despite their attempts to maintain a strictly friends only then a friends with benefits relation, the two end up dating. For the first time since her life fell apart, Cas is happy and it's because of Sebastian. The down side of working with your Ex is it means you'll have to see them again. Chris re-entering the picture complicates the situation further than anyone could've even imagined. Torn between Chris who was her forever and Sebastian who was her always. In one universe Cas picks Chris but in this one she picks Sebastian. Is the bond they have strong enough to survive working with her ex? Are the two really as compatible as it seems and do they want the same things?

**A/N this story was born bc I really enjoyed Cas and Sebs relationship in the original book so read one ending or read both, it doesn't matter. This is my multiverse and I have a lot of ideas for basically a What If style book for Secretly His.
