That moment when you go back in time to save the future but then you're 7 months early, you get stuck because your time machine breaks so some random guy asks you to be his fiancee off the street and you accept because you need money and all his friends are really hot so now you- wait... is this a K-drama?

I'm a 23 year old artist wanting to share the story that's in my head with the rest of the world. 7 months time is posted on weekends whenever I can. unfortunately due to poor health I can't post 100% consistently but I'm trying.
