And where exactly did I say it was unreasonable? I just forwarded what the developer has already stated and the reason behind it. By the way your math is wrong, as each girl has three "outfits", so it would be 300. Sure it may still be small if you compare it to a full update, but it is also a rather small thing, and from that perspective it is a lot of work for little gain.
Lastly, you already have 4 rooms (bedroom, toilet, living room and garden) they can inhabit, where you truly so modest to only ask for one more?
