Don't know if this is just a translation issue, but the writing appears to go out of its way to avoid stating the gender of Marika's significant other. Hmm...
Heh heh heh. Keeping it ambiguous, eh? Brace for the big reveal in the future.
As a matter of fact, we know preciously little about Marika's past. It's really unusual in a manga. I mean, normally, an author wants us to know all about her heroine, especially the important details, asap -- so as to better identify with her. In this manga, it's the other way around.
This makes me think there must be hidden skeletons in Marika's closet...
