Perhaps Guren really was obsessed with her all along, taking part in a long term plot and being close with an aspect of her in his mind, when she became his demon is obsession to some degree.

The dynamics as described above would have been interesting to see, and yet with Guren (spoiler alert) actually becoming a demon we are still shown (more spoilers! Stating even on the wiki, force of habit XD ) Mahiru's reaction with more possibly set to come is intriguing.
