Khalifa: Queen in the Apocalypse - Chapter 23: Tutoring Again (R-18)

The story revolves around Charles Karino, a Levaamu Empire mercenary aerial pilot who mans the twin seater reconnaissance seaplane Santa Cruz. One day, he receives a preposterous assignment: to fly solo over 12,000 kilometers of enemy waters to protect a girl named Fana del Moral. Fana happens to be the next in line to the empire’s throne and a girl possessing beauty “equal to 5,000 beams of light.”

This is a standalone book. There’s another series under the name “To Aru Hikuushi e no Koiuta” (Love Song for a Certain Pilot) set in the same world, but in a completely different place and with different characters.

A man in his thirties was standing in front of she-devil's grave, under everyone's watchful eyes, he dropped the flower to her coffin, his tone was full of ridicule. “Congrats on your death.”Next year he came, “I won. You lost to me and I will live well. Just rot in there.”Next year he came again, “I have a pretty girlfriend and I will marry next year. My life is good. Nothing to worry about.”Next year he came once more, “I will stop visiting and forget you! My life is better without you! See, I live well!”But he came again the next year and the years after that. People said he was hunted by his so-called arch-enemy. That even after death, the devil did not even let him go.He stood in front of her grave. His once handsome face had turned old and wrinkly.“Bei Sangyun, I cursed you. You are not allowed to rest in peace. You must be suffering there like me, right? You devil...”He might be the last one standing. But his life was the same as the dead's- lifeless and empty. He did not live well, he never once marry and his heart was never at peace.And it was all the fault of one person.*****Bei Sangyun was a big bully in high school.

They were classmates once in kindergarten and met again in high school.But one day, just a year left before graduation, the big bully suddenly changed.One day, Fei Chuan hesitantly opened his locker. The other night, the big bully said that she left something in his locker. He did not really want to open it. He was afraid a poisonous snake would come out of his locker. However, his report card was there. With gritted teeth, the young boy opened it.However, what appeared was not a hideous thing as he expected, but a bright pink letter with a little heart sticker as a seal.It turned out, the surprise was scarier than a snake.Was this a new form of torture?Since then, Bei Sangyun relentlessly chased the young Fei Chuan until the two got married.******This is a story of rebirth. The two arch-enemies who could not live under the same sky had become sweet lovers.

Chu Mu Yun relied on his story of 《Demon Realm》 to become a one-hit wonder in JJWXC, but the him who had written seven mental cases to abuse seven mental cases to death would never have expected that he himself would transmigrate into this shitty novel!
What the hell is this system on the bracelet?
And what the hell is this either propose to seven men, or suffer the taste of a tragic death experience under the hands of these seven people?
I just wanted to write a novel to satisfy my bad interests, who would actually want to get tangled up with a bunch of mad dog sad*st crazies?
