I'm just looking for manga recommendations where the female love interest is the type who is traditionally considered "undesirable." I'm talking bitches, sluts, whores, single moms, divorced, almost anything that you wouldn't normally expect in a typical romance fiction.

Maybe go easy on the gyaru romance. I find a lot of those stories are "she only acts like a roastie but she's surprisingly pure."

I only said manga because there is bound to be more diverse options, but anime recommendations are more than welcome, too.

I'm currently reading "Moto Fuuzokujou ga Kanemochi Tsuma ni Narimashita," where the female lead is literally a prostitute, and she eventually finds a husband.
