I really hop that this will advance their relationship. Either with Clara or Amelie. Time to choose.
I ship AmerHiruma. But I'm certain that author will choose Clara, only because Ameri is mature enough to not break if they only stay friends. Where Clara would throw a tantrum like a kid who can't have a candy (unless she have a maturing arc).
Actually, Clara can be strangely mature at times.
Also, she's been getting closer and closer with Asmodeous, so wouldn't surprise me if those two end up hooking up later on.
Also, the author has been pushing toward IrumaXAmeri for some time now. (Only one he went on a date with, only one he went to a public ball with and danced with, publicly went with her to that big event, and is only one he doesn't understand his relationship with her).
