I changed the lyrics 'it's been a long six months' to two months because why not?
I also just now realized that this song doesn't really go well, but I was thinking of cat and mouse chase kind of thing when this popped in my mind while listening to this song, so we're just gonna commit to it!
*= song lyrics

It was pouring in Gotham that night, but Bruce Wayne, philanthropist, billionaire, secret vigilante, the father of many children- whatever you want to call him-was on a mission to confess to a very special woman...

Hearing someone knock rapidly on the door, Selina Kyle opens the door in a black nightgown (it was after all... what time was it? Sometime in the late night, that's all Bruce knew-)
"Bruce? What are you doing here?!" She asks with a laugh.

*Stand there like a ghost
Shaking come the rain, rain
She'll open up the door
And say, are you insane, -ane?*

"I'm sorry for not telling you sooner! I know it's been a while, but..."

*Say it's been a long two months (Oh oh oh, oh oh oh, oh oh, oh oh)
And you were too afraid to tell her what you want, want (Oh oh oh, oh oh oh, oh oh, oh oh)*

"I love you Selina!" Selina's eyes widen at the confession.

"Is... is that all you have to say?" She asks, curious at where this was going, leaning against her doorframe.

* Remind her how it used to be, be
Yeah, with pictures in frames of kisses on cheeks, cheeks
Tell her how you must've lost your mind (Oh oh oh, oh oh oh, oh oh, oh oh)
When you left her all alone and never told her why, why (Oh oh oh, oh oh oh, oh oh, oh oh)*

*And now you say
I want you for worse or for better
I would wait for ever and ever (Ever and ever)
Broke your heart, I'll put it back together
I would wait for ever and ever*

"No... that's not all. Selina... I came here to ask you to marry me." Her eyes widen again and he repeats it.

"Selina, will you marry me? You will make me the happiest man in the world if you marry me!" Selina opens her mouth and then closes it, pausing to shake her head and smirk then looked up at the billionaire. With a nod and a genuine smile she says...

"Yes. Yes, I will marry you." And in a moment of happiness and bliss, they kiss in the pouring rain.

*And that's how it works
That's how you got the girl*

And they lived happily ever after.

Author's Notes

And finally, we are nearing the end. This was supposed to be finished back when I wrote Indescribable, the 3rd book in the Batfamily series, but that will be explained in the epilogue.
