^Tbh I'm pretty sure this is one of those ships that started in porn and just grew outward from there. That's not a bad thing really, just something that happens.
Lots of crack ships start that way. Like Sona x Ahri and ZAC x Riven.
Just from this picture alone, who ever says that Konatsu is not gay as heck is most likely blind. I mean, just look at how she wears her clothes! Definitely gay XD
I'm thinking the mysterious person in the picture above is obviously Kanan. Both have purple eyes (and similar eye shape) and the face shape looks similar. As for this image both Chika and Riko are telling whoever it is that You's theirs.
