Summary
Your husband was a lying, cheating, fuckface pig. But you can't leave him. Not because you're under the delusion that someday he'll change, but because you literally can't leave him.
You have died countless times, only for you to wake up on the night of your wedding anniversary.
No matter what you do, or who you choose, you always end up as Mrs. Gapryong Kim.

Summary
If God is real, then He has one hell of a sense of humor.
Life hasn’t been perfect. There were ups and downs, times where you wished you were born as someone else, someone prettier or richer or more talented, but you had reached a point where you were content. Happy, even. A promotion abroad, a new apartment with no roommates, delicious paychecks and what does the Big Guy do? He kills you. What’s more pathetic is that you died choking on chicken skin while celebrating your new life of independence.
Just when you were an official, proper, working adult of society, the universe spat in your face and now you were back to square one.
No, scratch that, you didn’t regress—you reincarnated as the only known daughter of a yakuza boss. Sounds fancy, you know, but this is no romance manga. Actually, it’s somehow worse, because your baby brother is the infamous Gun Park.

Summary
You died.
Literally.
The process itself was nothing special. The interesting part is what happened after. Instead of the abyss or paradise, a mysterious voice strikes up a deal with you in front of your fresh corpse.[I am the Villain Creation System, if you want a second chance at life, then you must corrupt the souls of various Mark Graysons across the multiverse.]
“Do I have a choice?”
[Of course! Agree to our terms, or spend the rest of eternity alone and conscious of your own nonexistence, unable to move on to the next life and barred from what your ilk calls Heaven.]
[ ˶ˆᗜˆ˵ ]
“...okay, sold.”
[Yay!]You successfully destroyed the lives of different versions of Mark Grayson, but when it's time to claim your prize, something goes wrong and you are stuck in this godforsaken timeline. What's worse was that they have found you.
"Come with me and we will rule the universe together."
"Be my wife and bear my children. No harm will ever come to you."
"After you died, no one could compare to you, not even your own corpse."You: (•_•)

Summary
You're reborn as a regular woman in the Lookismverse, but the world is different than what you've seen through your phone.
The main characters haven't even been born yet!
*This is a branch timeline and sort of prequel to "My Baby Brother is the Strongest Character," but it can be read as a stand alone.
