I respect what you are saying but there are a few problems. Yes the author wrote this for herself based on her ideal guy but the thing is the author isn't living in a fantasy. To the characters she created, this is their real life. Here is an easier way to understand what I'm trying to say. Imagine if we are characters in someone's novel, and your lover is the ML or FL. But then out of nowhere the person who created you wants you out of the picture because she/he thinks that oh! it's my ideal man or woman, so that person belongs to me. How would you feel? Although you say "destiny", the author just isn't the FL and thats probably because she doesn't actually have the personality fitted to be the heroine. My point is proven when she is being selfish and not thinking of how her characters would feel. You may be the creator, but that does not mean that everything must go your way.
Yes that's the point. But what I am trying to say is this isn't real for her. She can't realize this is the real world or actual human lives. But to her this is a novel. A fictional realm. For example in game u wouldn't mind killing a person cus it's just a game. So even though she is living in that world it's nothing more than a simulation (for her). So it's not right thing to do but she isn't avear of it. That's all. So u are right, she isn't fit to be heroine and she is selfish, but my point is to her it's just words in a screen.
All of you who hate the author... what did u expected! u wrote a story and imagine yourself as the heroine and created the perfect guy for it just to be a baystander. it feels like its the destiny stolen from u. and nothing is real in that world for her since she create it. so she is just altering a story in her mind not comiting a crime. （￣へ￣）
