I need help finding an old manhwa

I really need help finding this!

I first read it a few years ago, (I think 2-3?) and it got me into manhwas and so on.(It’s a smut/fantasy) It was on Manga Owl, and this is what it was about:

It was about a girl from earth, who had been pretty much kidnapped, along with a bunch of other girls from other worlds, and the first chapter is pretty much them all in a golden cage, waking up. They are surrounded by men in masks, and i'm pretty sure what happens is they get picked by them.

What I know about the characters is that one of the ML's has black hair, and one has blonde hair. It’s a reverse harem

The plot is pretty much her falling for both of the ML's, and at the very end she’s pregnant. The pregnancy system is weird in that world, it's like they are pregnant for much longer or smthn. I do know there is some kind of ranking system (no screen or pop-ups tho) with the people on that world.

If you need more details please just ask.. i'm begging you... i've been looking for this for years....
