Hi Ebi! I enjoyed the reading. This use of the yandere trope was a nice idea for the real focus of the VN.
I got a ...bad? ending first, it felt a bit sudden (suddenly thinking, "hell yes, Nagi will stay forever with me, she really does love me, I don't need anything else" felt weird because I, as a reader, was... "I don't trust you, I said I was happy you finally left"), but I guess it has something to do with the distress level I had at the moment.
At first, I thought Nagi would be some kind of demon, later a crazy fan, but once you advance enough, it gets really clear where it's going.
I liked the idea of the game closing after to finally deciding to wake up!
