Inspiration:
I think its pretty clear for KPOP fans especially ARMYS whats my inspiration but if you're not a KPOP fan you're missing out. My original sentence is if if you're not a KPOP fan I'm going to explain. Its a song title from BTS recent album.

The main character walks home from somewhere then realized she/he forgot to buy some stuff for something that is really needed for the day after so she went inside the first shop she saw. She went inside and she saw that she was the only person inside. Then the door slams shut.

Gonna start this from now on. Italics means author note btw. If you want to use one of my ideas but you still need more to start just comment and I will be more than glad to help you. :)
