I love this series. They're something so delightful about the way the change in Subaru's gender has been celebrated throughout the series. The frankness of the way the author handles sexuality like this is lovely. It's all very charming.
I'm kinda surprised to anyone at this point who is surprised by references to SA in this series... Komaki has been SA'ing Wakaba since literally the first chapter. If you can't say no then you cannot consent. It's that simple.
I don't hate the ending being 'good' for the main characters but...
