World-Destroying NPC, Stop! Your Yandere Girlfriend Is Here

Yun Qin is a junior employee at the Instance Bureau. Her job is to enter horror worlds and stop the major bosses who want to destroy the instances.

Those bosses are twisted, insane, and ruthless killers. The more fragile and gentle someone is, the more they like to kill them.

The usual methods of conquest were blocked, so Yun Qin chose an indirect approach.

He was crazy, so she went even crazier. And so...

On a ship about to sink, she grabbed the mermaid king, Siren, and dragged him into a shipping container, squeezing inside with him. Her eyes were wild and obsessive. "Darling, if we're really going to die here, then let's die together. I don't want to see you being gentle with anyone else."

In the serial killer's apartment complex, she tenderly wiped the blood from his body and prepared delicious meals for him every day. Once he had grown used to her presence, she locked him inside the house. Her possessiveness knew no bounds. "Darling, every second you're away from me makes me so miserable I want to die."

At school, she protected the pitiful boy who was being bullied. In front of others, she was completely proper, but in private, she teased him until his face and eyes turned red. Gazing at the beautiful boy before her, she wore a wild look. "Darling, you can only look at me. Otherwise, I'll kiss you until you cry."

The instances on the brink of collapse were successfully resolved. Having completed her mission, Yun Qin retired and prepared to find a normal, sweet romance.

But can someone tell her why her new boyfriend is happily talking about the instances she went through, clinging to her and insisting they stay together every moment, preferably with an item that sticks them to each other!?
