as someone who prefers ginga i kind of felt this too, that there IS some kind of preference leading towards kou...
but even then i think that ginga would be unhappy with anyone that isn't the one he loves the most; and it's pretty clear than other than yuu, he and kou are also in love too so if that love is mutual in any intensity, him leaving them would make zero sense
also just remember how upset yuu was when he thought ginga had someone else, he clearly cares more than it seems... but i still wish the author had made it more apparent during the time ginga was actually away from them :(
yeah, it really seemed like when ginga was away, that they didn’t give a fuck; they even forgot to pick him up :( like that rlly mad me kinda upset bcs it felt like ginga was their third wheel almost. but yeah, i rlly wish the author could’ve shown that ginga was actually important to kou and yuu </3
in this one I feel like the Ginga should move on, idc what you say, but I feel like he isn't getting enough love from Yuu as much as Kou is getting from him. You can see this in a lot of the chapters, like mostly chapter 3, where they were doing so fine without Ginga and everything, and even forgot about him, the look on his face when he first entered was enough, but when Kou is gone for a short while, Yuu feels the need to be with him and be with him wanting to do it with him, and I feel like in this and the other one, where you see before they all got together and Kou and Ginga were together, that Ginga has it pretty hard, he will be one of my favorites as in i feel bad for him, just not his perverted side.
