I want a novel set in modern times, where the MC and ML used to be lovers, or at least liked each other but never got together, whether it be in a past life that only the ML remembers, or just something that happens a long long time ago and the MC no longer remembers.
Have you read Stop Bothering Me Emperor? They both remember their past life though. You can also try Global University Entrance Examination. Spoiler It's not their past life but they were forced to forget each other
GUEE is one of my favorites, recently reread it to. I was thinking of trying the first one but a few reviews talked about the um...borderline racism towards Americans, so I'm not comfortable enough to read it. Idk how bad it actually is though.
I became popular after online dating with a big shot (MC's first life is quite sad & they did not get tgt. I forget whether one of them remember or not) Sacrifice to the devil (only ML remember) Second marriage of a wealthy old man (only MC remember)
I don't think it's that bad, but if you're uncomfortable with it, you can try I Have Amnesia Don't be Noisy. It has the same author with SBME but the pacing and flow is a looooot better. Spoiler The Main characters of SBME will have a cross over here but you can still proceed without missing that much info. The story is about the ML remembering the MC despite having an amnesia. If you like Entertainment industry type of stories, then this one's for you. Stop bothering me Emperor has a manhua, you can take a look and drop it if you really don't like it.
After rebirth, I became popular in the entertainment industry Rebirth of a cannon fodder from a novel
