Hi! I'm Ren, the new girl in town. Or you could call city... 
I recently moved to Seoul, in South Korea because of some financial problems. But after the first month I was here, I apparently lost my memory due to a bus accident.
I wonder how that happened? 
No one is telling me anything other than
"It was just an accident.
"Don't get too worked over it."
"AISH, STOP BOTHERING ME."
And so on.

So what really happened?
