Did they ever talk about Su Have to moms or was that a Fanfic thing? I can't remember... oh well, anyway I have seen one other fic like this before and I hope you fix where the other seemed to mess up.
It never let Keitaro and Kaolla build anything between them after get hitched... or before either. The Inn group just got in the way, over and over again when ever they tried to relax, to the point where it got so lame and you had to ask why the writer wrote it, if it's just a constant loop.
So please, please let us have another quality Keitaro/Kaolla I think it will raise the number to 3, if that.
Oh and good work on what was there so far it has promise.
