(my English is poor so it might be a little weird)
To be honest, I didn't expect much at first. I didn't even know it was a yandere game. I thought it wants people to know hero would also be tired after work and we should recognize the other side of him. (though the results seem to be kind of similar)
So when I finished playing the game, I definitely felt very surprised. I really like ray , but interacting with him do make me feel very heavy, feeling that I have to observe his reaction to decide what I should say.（not a negative comment I like the tension ) I don't think they changed much in the after story, either Binary star or Ray still scares me a bit(good thing I am not MC otherwise I would screw it up)MC has quite a long way to go, especially when you have to cope with someone who can destroy the earth.
The last scene in Ray's route is my favorite, filled with a sense of divinity. The existence of MC helps him keep humanity and create connection with the earth, which makes me feel amazed and touched.
And after game, I feel more about the title: the binary star refers to two sides of Ray, his ability, and the hero MC. In a sense, they do sacrifice themselves to save the earth, this great cause is grand enough for them to transform from a regular villain into an unknown hero.
(also a little wonder know whether in other routes the earth will be destroyed. Why did Ray stop chasing? Is he disappointed in the MC?)
And I also want to know Ray's age, just a little confused because I think he doesn't look that old, maybe it's just a flirtation)
Thank you for creating such a wonderful game, I've played Favor and look forward to it as well!(Though still want to see more Ray)
