I will take her not voicing that Miyu died and only letting him arrive to that conclusion by being silent as a hint crumb that this Miyu is the real one and that the dead one is the fake one, thank you very much (absurd levels of coping, I know).
Just binged the available chapters, both female leads are just soooooo gooood, they both feel like a perfect match for the protagonist, I can't bring myself to root for just one of them!
WHAT DO YOU MEAN THIS IS ALREADY ENDING??? It had a cool and original premise, compelling characters and a main duo with great chemistry... Axe-kun sure is cruel...
