SEARCHING FOR A BOOK I READ ON WATTPAD A LONG TIME AGO

Sad ending.
She's a photographer who took a pic she rlly shouldn't have, completely on accident. Gets taken by the boss to a brothel type establishment. He gives her a name and gets her to be one of the girls. She becomes one of his favorites. Gets friendly with the other favorite her name I def remember being Bleu. She's totally gone, mentally, because she's being pimped out as a sort of prize to the high ranks. And they are not often vanilla. Not rarely the two of them are put together and because they both are going thru the bad, when told to grind mirrors they treat each other very gently. The boss knows very well that she would off herself if given the opportunity, so doesn't even allow her to go out at first, then only if Bleu is there and finally when she's attached to Bleu and wouldn't want to impact her badly he lets her go look at the sky alone. She ends up pregnant with the boss and so stops receiving customers until she gives birth, he tells her the kid didn't survive but actually puts the baby into the system. Her mind is even more gone after that and Bleu tells her she's planning to escape. They end up running away but while the boss is in pursuit she kills herself in front of him so Bleu would go free. She, from the beginning, planned to do it that way, knowing that's the only way for at least one of them to go free as she can't function in normal society anymore but that Bleu could.
Bleu was imprisoned a lot longer, since she was a kid ,as she was taken because of her sister's debts, but only started taking costumers when she was older. The 2 of them were the only ones he gave names and not basically codes, as there were many girls there but their number was fixed, so when one died or was taken somewhere else they'd get another and give her the same name as the one who was gone.
It ends with a chapter set in the future, with the boss visiting a cafe and tipping the waitress really well, we find out the waitress is the kid between the main chick and him, who left the system when she was adopted by Bleu, which makes it more obvious what mad skill Bleu had, to find her a few years after her birth, and that the boss kept track of them both, but didn't do anything about either.
I really really want to find this, the other thing I can tell you is that the author was writing a spin of/sequel about Bleu which was exclusively put on Radish, but at the time Radish was unavailable in my country, and I'm not sure if it's still on there now.
