Yeah there's not a whole lot. It's just not one of those stories. If U remember the top, jay has a personality(?) disorder and doesn't really feel emotions. And yoohan is quite obviously depressed asf and has no real will to live. They definitely love eachother, just in their own ways
but I do feel it now in the side stories. This is seriously getting cuter and sexier ლ(´ڡ`ლ)
