It could mean that the person considers themselves to be the best or most dominant in the realm of magic novels. Maybe they have a vast knowledge of magic novels, or they think their writing of magic novels is unrivaled.
Poison Barbarian King's description of LOL was rather vague, and it was unclear which novel or manga he was referring to. However, according to my knowledge, if the word LOL appears in a novel or manga, it usually means that League of Legends is a very popular multiplayer online competitive game. In the game, players needed to form teams to defeat their opponents through strategy, skill, and teamwork.
It could mean that the speaker views themselves as something not real or existing only in the realm of imagination. Maybe they feel like their life is like a fictional story, full of made - up elements or that they are a fictional character in a sense.
In real life, 'I am the writer of my own story' implies self - determination. You are the one who decides how to react to different situations. If you face a difficult situation at work, you can choose to either give up or find a solution. You also get to choose the kind of person you want to become. Do you want to be someone who is always learning and growing, or do you want to be stagnant? It's all up to you. You are the one writing the plot, the characters (which is you), and the ending of your life story.
A very experienced author who has written many successful magic novels could claim this. For example, J.K. Rowling with her 'Harry Potter' series has revolutionized the magic novel genre. She could potentially say this because of her great influence.
It could mean that you have an inherent quality or essence that is similar to a classic novel. Maybe you have a complex, multi - faceted personality like the rich characters in classic novels, or your life story seems to have the depth and timelessness of a classic narrative.
Perhaps it implies that there are other elements or parts of the story related to 'her' that you don't encompass. For example, if 'her' has a complex backstory or different plotlines associated with her in the novel, and you are only a small piece of that larger narrative.
Perhaps it implies that the speaker doesn't want to be associated with the qualities or the plot of an online novel that features a female character ('her'). It could be a statement of individuality, saying that the speaker has their own identity and is not part of that fictional world.
Well, 'only i am a reader novel' might be a statement indicating that the person feels they are the sole individual engaged in the act of reading novels. It could be that in their immediate circle, no one else has the habit of reading novels, so they feel special in this regard. For example, if they are in a family where everyone is more into watching TV or playing games, and they are the only one who enjoys getting lost in the pages of a novel.
I have no idea. It's kind of a confusing phrase without more context.
