I see that a lot of people doesn't like that Yuu and Kou had some time alone. I think it's okay that they want some time for them. Just like when is for Ginga and Yuu, or Kou and Ginga.
Or that Kou has a lot of screen time. Of the 3 chapters, I think that only happens in the third one.
I don't think there will be only 3 chapters, so don't worry, there will be more for all of them.
Obviously both of them loves more Yuu, that's because they had these feelings since childhood. But obviously they also had feelings with each other. Just that not as strong as the one for Yuu.
All of these is just my opinion

There is something similar to this?? I need more!!!!

This story is not exactly like that one but it's funny and has Gender Bender
I loved how he asked
"Do you like cats?"
It was like this was the decisive question. I belive that if he said that he didn't like them. He wouldn't have accepted!!!
