Naturally they are 18+

In this reality, everything went wrong. A girl named Marinette Dupain-Cheng was either never born here or her life was tragically cut short many years ago. The famous bakery, which could have become the heart of the neighborhood, had long since gone bankrupt and closed. The building was falling into disrepair, and the room where a normal, cheerful teenager could have lived was now filled with dust, cobwebs, and peeling pink wallpaper. It was a perfect, hidden place.
It was here that three distorted versions of Marinette invaded, tearing through the fabric of the multiverse. They were fleeing their shattered worlds. Each of them, in their own way, had lost their beloved (or not). And when they learned that in this universe, yours, you were still alive, they came for you.

Guys, I'm sorry if there are too many mistakes in the text, as I already said in one of my bots (which I deleted😶‍🌫️😶‍🌫️😶‍🌫️) English is not my native language and I mostly use a translator... so I apologize again for the mistakes
