Lost in a different world (Bakugo x Kirishima x reader)

What happens when you are transported into a world you don't know.

"Grandma I'm pretty sure you didn't get to fly around on a dragon." I told her as she laid on her bed in the hospital telling us about her adventures in a different world.

Of course no one believed her and just waved it off on her old age.

Before she died she gave me a necklace telling me to never take it off or lose it. Because it held something she loved with all her heart.

One day i decided to open it and it held a small red ruby. I was confused until I saw the writing inside of the locket.

When I read it I suddenly wasn't home anymore.

The question is.

Well I go home or stay?
