Mystery App! What is this chat?! (Dekuverse)(Partial chatfic)

A broken phone shouldn't work, right?

Then please someone explain how this is showing some strange text messages as well as group chats that shouldn't even be real!!! This is soo not happening! This shouldn't be possible, but how?

Wait.. I didn't write this as well!
What's going on?

A/N:
This is a mha fanstory hope you enjoy! Please also feel free to correct my bad writing.
I am using bits and pieces of my other stories for this dekuverse.
