Hmm lots of people complaining about the story. I just read through the whole thing and everything makes sense to me. My guess is it's the long gap between releases that makes people feel that the story is disjointed. I guess now that I'm caught up I'll get to see if I feel the same way after a couple of months. Honestly monthly series are always like this when you follow them as they come out.
The question should be why Seran doesn't like her, when he's shown running after any skirt passing by? She's even a princess! And there's not really other girls fighting over him, are there?
