Rental Pet Boy

From Chibi Manga:

It's troublesome to take care of pets on a long term..but if it's rental and only for a short period of time, there will be no strings attached?! On top of that, the pet is actually a wonderful boy acting in replace of an animal...? Will you be choosing the cold and cool cat character or will you pick the wild and exotic tiger? the dog that is a faithful & gentlemanly? You can have any ideal boy!!
