Aliens have shown up on earth some years ago. A human decides to become landlord for a bunch of female humanoids from various cultures. Great stuff about cultural differences, communication etc., and Edo-chan is the man to master it. This is so sweet. One of them is a really tiny elf, and he serves coffee to them all. For the tiny one he considers some cups and then goes looking for a thimble. You can't avoid snickering when you are reading the book.
It is 69.000 words but it is free (the sequel only 1.99USD for another 60.000, which is fair). There table of contents has meaningful captions so you easily can find again a chapter.
