[System + parallel worlds + intense push and pull + pure love]
Turns out you really shouldn’t pick things up off the street. For no apparent reason, a System dragged her into doing missions, and her first task was to bully her soft, adorable twin brother!
Everyone else transmigrated into someone else’s body, but she arrived in her own. She was impersonating someone, and risked being found out at any moment.
To get home, she had no choice but to follow the System’s orders and torment the so-called NPC in this game.
Then she learned that this was a parallel world, and every “NPC” was a real person with a body and feelings.
Despite her constant bullying and insults, he didn’t hate her. Instead, he obediently asked, “Sis, are you not going to be mean to me today?”
Her: “???”
At some point, the way he looked at her grew more and more improper, more and more obsessive.
“Big Sis, I’m pure. I’m not dirty.”
What?! She was impersonating his actual little sister. How could he sell his body just to get what he wanted?
Only at the very end did she finally realize that he had known everything all along.
Faced with a life-or-death choice, after wavering and hesitating again and again, she finally fell into his trap and sank deeper and deeper.
