Qidian describes it as an ancient romance.

This has crossdressing and multiple fiances. But I think you can figure out who becomes the husband by looking at the title.

After crossing over, she became a disregarded and abandoned concubine in a cold palace. What? Her living expenses were cut off in the palace? No... more>> problem, she had a spatial artifact, so she didn't worry about food. What? The emperor turned out to be a greasy, fat middle-aged man? No problem, she earned enough money by selling illicit books and planned to leave the palace. What? The incredibly handsome man in front of her is actually the emperor? His enlarged charming face dangerously approached her and he asked, "Beloved, where are you going?" <<less

From the author of Dreamer of the Spring Boudoir. Expect strong women, regretful ML, and angst.

This is a great book. Highly recommended.Flying Lines had translated many chapters, then removed it from NU.  Now someone else is has started translating from... more>> the very beginning. I think FL might have other chapters on their site. <<less

The reincarnated MC is a salted fish.

Brought to you by the author of Greetings, Ninth Uncle. . The MC is the fake twin daughter that was switched at birth. The ML is the true male twin. At first they didn't get along. They knew they weren't related long before falling in love.... more>>

There's some mystery solving too. <<less

Excellent translator.  MC Very OP.

MTL-ed it awhile ago. It was pretty good. It's about this girl that realized she's in a novel and has 2 rivalries. One is with her cousin that has a system behind her. The other is with her dad's new concubine.  Except it turns out that the concubine is actually the outlaw prince in hiding. His uncle the emperor wants to kill him because the prince is the legitimate heir to the throne.... more>>

I think the author wrote this before Greetings, Ninth Uncle. <<less

This is a nice pleasant read. No angst or dog blood. The MTL was easy to read, and I went through it quickly. There were... more>> side stories that weren't available yet. <<less

Smut. Translator says ML is extreme yandere that unifies the warring states.  I read a few chapters. This has non-consent, dubcon, etc. So don't read... more>> if you don't like that sort of thing. This isn't just obsessive love, it's crazy psycho love. Mostly smut. <<less

This is a romance and mystery.

MC falls in love first.

According to the reviews and the translator, the blurb doesn't match the book. The ML doesn't cheat.  He has bad EQ.  And because of something... more>> a close relative did to harm a lady, he felt obligated to make her a Concubine.  After that, there's a whole bunch of misunderstandings. <<less

I read somewhere else that it's really funny. Tried to MTL, but I don't understand the slang and idioms.

Finished. It's okay. The ML isn't as brutish as the reviewers have suggested. He starts out as a dolt with low EQ and slowly becomes... more>> more enamored with his wife, although it's hard to say why. <<less
