The Tyrant Empress is Obsessed with Me - Chapter 39:

After being summoned in this other dimension world, all of the people that were summoned had their classes awakened. As someone that doesn’t even know English, Kim Sunhyuk had awakened as the lone Dragon Rider. But wait, there are no dragons?!?! They looked down on him, shunned him for being worse than a regular soldier, and called him a dragon-less rider. But little did they know that he would soar the skies on one above them.

In the year 2025, humans awakened with the ability to summon mighty beasts—capable of destroying terrains, breaking the laws of physics, and creating wonders limited only by one's imagination.But before these blessings came a curse.An alien face appeared from nowhere and threatened all life on the planet, leading to the greatest war in human history.In the aftermath, the human race and the alien race were forced into a shaky treaty that could be broken at any time.Years later, tests for summoning abilities began for the next generation. Those who awakened low-grade summoning would be thrown to the gutters, while those who awakened higher got to join great factions after graduating from the academy.Kairos Veyl, the blank, calculating student, pulled his hand from the massive crystal pillar and stared at the large beast before him.“This kid—he just got a LEGENDARY SUMMON.”A legendary summon? The greatest class of summoning. However, with this class came a risk one would have never guessed.

One day, Luo Jian woke up from his sleep and found himself in a locked chamber where the door and window were all sealed. A note with a few lines written on it was tacked to the wall: “Escape from this room within an hour, otherwise, you will die.”

There is a sequel called Reincarnation Night (轮回之夜) that takes place in the same universe but has different main characters

Unhinged Yuri story set in Seoul.------“Like a prey waiting with a trap, I missed my predator.I missed her touch in the places I’ve never been touched.I wanted to hear her sing the songs that I’ve never heard.”------As the blood dripped off the knife she held firmly in her pale hand, I saw my reflection in the cold blade that had just taken the life of a man.I dreamed of magical moments like this every day.Something - someone to come and free me from the suffocating monotony of normalcy.She stormed into my life brandishing death, and in the moment of madness, my heart fluttered.Then she came to my place, uninvited. I treated her wounds and fed her. She slept on my couch like a cat. We started our lives together. Death bound us like the knot of tie I fixed for her as she left for work - to kill, kill, and to kill again.I spent countless nights sitting in darkness, on my couch hugging my knees, gripped with worry and excitement. I prayed for her safe return home, but I did not pray for the souls she’d be sending to hell.But she always returned, like a stray cat coming for food in the back alley behind a restaurant. I was the cook who put out the food for her, stroked her, and gave her shelter.A stray cat. A great feline predator. She was mine and mine alone.Together we laughed, alone I cried.Together we laughed, alone I cried.But I think we also loved.I think.------This is a dark and twisted psychological slice-of-life romantic comedy with a sprinkle of inspiration from the noir genre.
