When watching TV series or reading novels, I always want to be that happy heroine. She has the domineering and strong love of the male protagonist, has the solid protection of the supporting actor, has one or several good friends who will be loyal until death, and is doing what she likes. Everything looks so perfect, like a dream. However, reality is not that dreamy, and there will always be various dissatisfactions. At this time, if you imagine yourself as a character in the story, you will feel that everything in front of you suddenly becomes so beautiful. Of course, for most people, this is just a thought. After all, they have to face whatever difficulties they have to do after they have finished being in a daze. However, there is such a girl who, by chance, enters the world of the story. Will she have a vigorous life like a heroine?
