I think a great comparison for this is Naruto and Sasuke. Naruto was absolutely obsessed with Sasuke, but as a very close friend, equal to that of family. I've only watched the anime and probably won't read the manga because I'm just an anime person, but as for the anime Yu has blushed a few times when complimenting Shinoa or while she has thanked him for saving her. That may be a hint, and furthermore, I really want to emphasize this, even if you are gay, you still don't want to bang your best friends. On top of this, you surely wouldn't bang your brother. As of now, that is what is shown throughout the anime. The two are very close friends, to the extent as to see eachother as brothers. After watching more of the anime Shinoa is what causes Yu to look away from Mika. Shinoa also seems to be the final straw that throws him into his demon transformation. That's why I compare this to Naruto, because I believe that to be the same case. Frankly, Mika is also far too obsessed with Yu. To the point where I'd say he's insane.

I'd like to edit this a bit more- I believe Mika is starting to represent Yu's past, and the things he has to let go of in order to move forward with life and take new responsibilities. I think this is shown right before Yu transforms for the first time, as Mika is trying to keep him from defending his new friends. Mika is also very territorial of Yu, which to me shows that if the relationship did become canon, it'd be pretty damn abusive.
