As the house became cleaner and looked far better on the outside, Kyoya did the magic trick and summoned his own. His house then got strengthened by the wood from the 19th floor causing its design to change a little.
It matched with the forest from the 19th floor and Kyoya also designed the roof to look like autumn hot leaves here.
The ladies and the husband himself also could feel that the interior was warmer. No one felt like sleeping under the blanket and Xaya even commented once that she doesn't need pyjamas here anymore!
Kyoya felt like stopping his wife, but since there weren't any men in his party right now, the husband eventually lost the battle of arguments with his wife! Even Rosa's remarks didn't help and so Xaya was sleeping naked with her husband while others beds were rather close.
