I think it would be easier to answer this question if you just accept the fact that Kou is just so shippable. As you will come to see later, there are more people pinning for Kou. Personally I can see the chemistry in all of them have with Kou. Kou's character is just so amazing. Like his past life, and even more so now, he is all encompassing of everyone.
Kamio and Kou have an one sided dependency, and I find that a plus for the pairing. Kamio was very antagonistic towards Kou in the beginning, and becomes unable to live without Kou. In the beginning it is more out of necessity, but I think Kamio have come to care about Kou in his own way.
Then there is Jun. First they are brothers (cousins really) and that seems to be a hit in the yaoi community. Then there is also Jun's possessiveness of Kou, and how Kou treats Jun. There is something about possessive lover that gets you kind of excited. And this point can apply to all three pairing, since it is present in all of them.
I think a lot of the KouXJun shippers is also due to the fact that a lot of readers see Jun as Garai, and they want Garai to be with Raki who is Kou
Not me.....i just love incest route.........
Let the game begin muahahahaahaaaaaa.......

Question for Kou and Jun shippers and Kou and Hazuki shippers, what makes you ship Kou with Jun and Hazuki respectively? I’m honestly really curious. For the record I’m more on the Kou and Touya side but I don’t really have a strong emotional connection to them as characters or as a couple (I honestly find all of these characters annoying to some degree but I love this manga). I want to know because when I decided to read this, one of the tags (or a comment I can’t remember at the moment) I saw was love triangle, which made me hesitant to read it because I intensely dislike love triangles. But when I read it, I didn’t get the sense that there was a love triangle at all (at least by what I understand to be a love triangle=one person has feelings for two people and can’t choose). Kou only sees Jun as a brother and if I remember well, at some point Kou said he was scared of Hazuki but now only sees him as one of the warriors, a valued comrade. I don’t get the sense that Kou views either Jun or Hazuki in a romantic/sexual way, so I’m curious. Why do you ship them? Please explain it to me because I want to see your point of view. Also, please don’t fight in the comments over ships. Thank you! ヾ(❀╹◡╹)ﾉ~
