I am the first leviathan eater of humanity again:Futa - Chapter 1: After all these years

I had a supporting role in a modern fantasy.

The loyal dog of a villain with an angel’s name, Cheon Sa-yeon, and an unfortunate supporting character who died on his behalf, Han Yi-gyeol.

In order to escape from Cheon Sa-yeon and survive, he must use the protagonist, Ha Tae-heon.

But Ha Tae-heon, who he thought of as a lifeline, was infinitely indifferent to him. Rather, Cheon Sa-yeon showed interest.

But besides that, something strange happened.

The events that occurred in the original story had advanced, and the gate and monster levels had risen. Even the people were “different” from the original.

The original version I was trying to use was wrong.

“My only regret was.. living like a puppet for my sister!”Olivia Witherland had no one but her sister in this world. So when her sister Oriana married the duke of Aykroyd and became the duchess, she had no choice but to follow her there. Despite knowing that her sister had killed the previous duchess and going to harm the child left behind, she kept her eyes closed. But when the child grew up as Demon,he killed everyone including her and the innocent kids, Oriana gave birth to.Olivia regretted that her silence had harmed not only Damon but her innocent nephew and niece. Everyone was killed, but the killer lived a hollow life too.But fate gave her a second chance. Would she be able to save everyone or would destiny play a cruel game again?

I thought being laid off from my job was the greatest of my worries but I just had to wake up in a ship's cockpit after my space game crashed. Now I have no map, no friends and no money.But that's ok, I've started from the bottom before! With my starter ship I will scour through space as a Mercenary and maybe even start up a Mercenary Company while I'm at it! This ain't my first rodeo in space after all!Except... Apparently my crew members are weird?The guy who bumped into me yesterday was found sliced up and floating outside the space station.The girl who tried to honeytrap me was reported missing with only a finger found in an alley.And then that merchant who scammed me had his entire ship blasted into bits by unknown vessels the very next day.Some people say my crewmates were behind it but they must be mistaken, right?I only know one thing for sure...In space, no one can hear you scream...

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.
