Books similar to The Rosie Project

I just read The Rosie Project and I really liked it.

I’m looking for something similar. I know there are 2 more books in the series and I’ve just ordered them.

I’m not necessarily looking for a book about characters who are on the spectrum but rather just something that is light-hearted, funny, easy to read and not too long in length.

If it is a romance book, it would preferably be from the male perspective, and a MF relationship, but it must have a humorous undertone.

Thank you!
