Thanks Mr2005. Me and my brother read this in one sitting in the middle of the night and it’s awesome. Translation is such a neat trade, and I’m glad I got to read this!
While I’m at it I’m going to note that as a pretty clear subversion of the “Savior” genre I hope the protagonist gains the ability to find hope in her own future. It’s a story with so much focus on mental health that I’d be pretty caught off guard if Yotsuha never got over her codependency with him. I hope they can both become people in their own right, even as they grow together.
