When our protagonist becomes the game character Jun Karentia, she thinks she has it made. She may be just a lowly support mage, but with her knowledge of the game, she knows she can finagle her way to the good ending following around the main character, Fabian. The problem? This game doesn’t end after one playthrough. Jun is prepared to guide Fabian through the second playthrough to the true ending when… Fabian abandons her. Now the Grand Duke Mayer Knox—captain of the Dark Knights and the secret final boss—is determined to have her join his party. Can Jun turn the final boss into the main character? Why is Mayer Knox so intent on having her in his party? And when will these rumors about being his lover stop?!

A polite and lethargic boy was reincarnated in another world as a vampire bishoujo.

Two years ago, Nina married a man she had never met. She didn’t know his name or his age; she knew nothing about this person she was married to. Their marriage was nothing more than a contract with conditions, and one of the clauses was that she should not sleep with another man.

With the compensation she had to pay weighing her down, she decided to draw up a divorce agreement on her own.

When she finally met her husband to hand over the papers, she was shocked to find that her husband was none other than the man she had “cheated” on him with!
