I read this Novella after completing Rain and Nights' story in the series, and I really think it fit quite well there. 

I knew enough about Sora and Bragi from those two books to walk into this Novella, not needing a whole bunch of additional information, but also really excited to read their origin story. 

I fell for both of them so hard. Poor Sora just trying to save her brother and Bragi with the absolute biggest heart. 

This Novella was, without a doubt, 100% swoon worthy.
