All My Cringe Writing Came True

After transmigrating into the world of the cringeworthy black-history novel he wrote during his chuunibyou phase, Iven had only just managed to escape imprisonment when he gradually began to realize that something was very wrong.

What do you mean my archenemy is actually a woman disguised as a man?

What do you mean the main couple I ship wants to take me back as a blood thrall?

What do you mean the villainess I took in is offering me her loyalty?

Many years later.

Iven looked at the women asking him which one of them he was going to register his marriage with, cold sweat running down his back.

There seems to be something very wrong with the black-history novel I wrote.
