What is this form: Vb + あう + Noun


As I was browsing the Nintendo e-shop, I noticed a [new
title](http://social.gust.co.jp/shiroyuri/) whose tagline is:

> 美少女｛びしょうじょ｝と美少女と美少女が惹｛ひ｝かれあうRPG

(Don't judge...)

How to interpret this 惹かれるあう? I understand that the appeal of the RPG are the
(numerous) beautiful girls, but what nuance does it bring?

My dictionary only gives 会う/合う as possible writings for あう but I am not sure
how to interpret it.




A verb + しあう means "to do together(each other), so 惹かれあう means "to be
attracted to each other".

美少女と美少女と美少女が惹かれあう modifies a noun "RPG".
