The Mafia Luna

So it's like Library of the heavens path? (Not sure if that's the correct name). What you described here is exactly that.

One of the best romance novels I've read. The whole story is well built and structured (there will be no love at first sight and nothing random like that) I loved it very much .

Ps. If you are looking for a s.m.u.t, this work is not for you. There are scenes like that but it is not the focus of the work.
