You’re not fooling anyone, Koruval. Especially not Mizha.
The process of grieving is a strange one. It’s like the body goes on some low-functioning auto-pilot for a while. There are simply days that I don’t really remember from when my grandfather passed away, and I was hardly myself for the portions I do recall. Everyone responds so differently. In this case, Koruval hides his grief, and Mizha avoids it, but both are struggling underneath the facade.
