Isekai / RPG game like / Fantasy World fever 3

Bastard princess sold off to marry tyrant emperor. Instead of killing her as she expected/ planned, he ask her to become the vilainess above the tyrant?!

Hilarious. The more I read, the more entertaining the plot becomes. The charcacters including the side ones all have interesting double layers. Innocent MC but neither Meek, neither OP strong. Put up a damn act though. Technically an isekai as Novel author reincarnated as Saintess instead of MC but she's a side character.

Spaceship sergeant was transmigrated into noble lady body. Now she will fight to survive against those after her life.

Surprisingly interesting and funny. She found back her bracelet with an AI and use it to her advantage + try to find her old spaceship. She has a weak body but compensate with her free spirit and military knowledge. Competent OP ML (aloof at 1st glance). They have a nice casual friendly relationship.

Office lady transmigrated as a maid at the Emperess palace in a BL novel (but not a naive romance), she then became new born crown prince's nanny. But who is this maid she became? And what is her role in this royal mess?

Unique slow pace mature story. She wants to stay neutral in the political fight to survive. No og body memories but mysterious past. Expressionless Empress (i pity her). Og Protag feels so eerie. Other characters are interesting too. Interesting but where is this going?

With the "FL counterattacks system", MC's an agent who transmigrate into various novels and get revenge for betrayed woman against bastard ML and FL.

Mc is a dominating, cunning, calm and ruthless lady.
This is basically a stress reliever, watching real retribution against annoying cliché "main" characters. Refreshing how, in some arc, whole new perspective are givens, not making it too repetitive.

Cheating men must die prequel. MC first mission and some hint about her past.

Basically same as usual but MC started with zero cheat (1st mission) and against another super experienced host with love system and lots of cheats.
C12 seems complete?
