(Not horror, possibly more absurd comedy)
Shen Tangli, a remarkable young woman in the prime of her life, is sent into an infinite-flow game because of her ex-boyfriends' curses.
As a perfectly sane, highly civilized human being, Shen Tangli is never stingy with her friendly responses to the System.
System: "Welcome, player..."
Shen Tangli: "Welcome home, Grandma. Why didn't you prepare a big gift?"
System: "Shen Tangli, Player Number 1444444."
Shen Tangli: "Thanks. It's one in the afternoon, so I'll call you One O'Clock."
System: "..."
System: "Player's starting location: the final dungeon's battle arena. Dungeon level: S. Mission: draw a life-sized human figure of the boss. If you fail to complete the mission inside the dungeon, you die outside it."
Shen Tangli: "You sure do have a lovely bark."
After entering the game, Shen Tangli says, "So it's actually real?!"
Other players' missions: avoid the Boss and survive until the game ends. Shen Tangli's mission: start right beside the Boss, then strip him.
Fortunately, capable people never complain about their circumstances. Shen Tangli was born with a talent: she's a human camera. Once she's seen someone, man or woman, she can reproduce them to scale without a problem.
But, Boss, you could at least not wear so many layers, or lie under a coffin lid and a blanket!
Shen Tangli reaches out with a trembling hand, only to catch sight of the Boss's face.
An ex-boyfriend?!
So many ex-boyfriends?
Are ex-boyfriends a social species?
Achievement unlocked: "Wanted by the entire dungeon from the start."
Other players: "Thank you, Shen Tangli. I hope every round I meet a good person who draws the monsters away. The Boss walks right past me without even looking."
The innocent little girl, Shen Tangli, who has been hiding away to draw her sketch, looks at the figure she drew from memory, her face ashen.
Impossible. Her sketches could never be wrong.
Unless...
A hand suddenly reaches up close and taps the drawing board, pointing at a certain spot. "Isn't it a little too small?"
Shen Tangli: "???"
After spending so much time studying her ex-boyfriends in the dungeons, Shen Tangli realizes that her drawings are usually wrong because those bastards have some strange extra parts growing on them.
So it's no wonder she breaks up with them so quickly. What can she do when every one of her ex-boyfriends isn't even human?
A heroine who does whatever she feels like but has terrible luck x ex-boyfriends with all kinds of personalities.
P.S. Most likely multiple versions of the same person, but definitely 1v1.
Theme: Be independent and strong, and bravely explore new ways forward.
