Does someone know the order of the series?

I think the order is.. Ayu no Monogatari, Host, Reina, Pao, Real..
The last two are drawn by different artist.And I love artstyle from Pao no Monogatari the most though, Ayu looks more beautiful and kind.
But I kinda dislike the 'Real' one.. the artsyle isn't to my liking (Well, I said it politely). And Ryuji, the manager of host club, is so ugly that hurt my eyes, same goes with Shou and Takashi.

One more thing, for Pao story.. I think it's alright to read them after reading Ayu.. cz Pao's journey's also end as he stayed with Ayu till her last breath.

Thank you (づ￣ ³￣)づ
