The reading for this is messed up. You have 物 as もの, which is fine, but 語 decides to go all crazy on you. Maybe you've heard the word ものがたり before (it's in some film names / book names). If not, think of a story being told about a great gatling (がたり) gun that wandered the land, mowing everything down in its path. It's a terrible legend, but what if it were true???
I think she's acting like she's the main character of a story.
The Tale of the Bamboo Cutter is a famous Japanese legend.
I’m writing a story right now. It’s about a sad guy who is obsessed with puppies.
