Need to add series to books

[Raven]

I need to have new series crated called "So, About Last Night" and have the following 2 books added to it.

The Don (Book 1) https://www.goodreads.com/book/show/2...
The Penthouse (Book 2) https://www.goodreads.com/book/show/2...

To be a series on Goodreads, books need to have more than a common theme -- like characters in common, an overarching storyline, a shared universe, etc.

How are these books connected?

Here is how I have the series described on Amazon

Series Summary — So, About Last Night
One night. One choice. No guarantees.
So, About Last Night is a collection of short, sultry, and emotionally charged BWWM romance stories—each beginning the morning after a night that changed everything.
Maybe it saved a marriage on the edge.
Maybe it reignited something that should’ve stayed buried.
Maybe it meant everything… or nothing at all.
These aren’t love stories wrapped in bows.
There’s no promise of forever.
Only the raw, unforgettable truth of what happened last night.
Each standalone is a glimpse into passion, consequence, and connection—where heat meets heartbreak, and love isn’t always the answer… but it’s always the reason.
Some nights end in silence. Some end in blood.
But they always, always begin with desire.

It doesn't sound like there is a connection between these stories.
