Mr.author, I have to say, you are trying hard to imitate the Little tyrant, you changed the beginning sitting, so you should change the mindset of the MC after all the different is circumstances between the two MCs is big, there the MC only remembered his past life because he encountered one of the main cause of his death on top of that he is a trash villain character and a minor one on top of that in a very popular game so and when he remembered his past life and recalled the details of the game from his memories, he naturally has every reason to be scared to death, it's just some so many people want him dead even if he chose to hide in his room and do nothing, but when you come here and mentioned that the MC reincarnated in an unpopular game world with the memories of just the first 10 years of a side character, then you are just forcing it when you make him find the connection instantly with the game because you make it sound like he remembered his life as a game character and not some normal 10 years old boy, also for unpopular game it should be on the back shelf in his mind not the only thing he think of when he face somethnig supernatural like reincarnation and magic, actually it would make more sense if he doesn't recognise the world until something big happened like the news of some important event from the game happened in his current world, also, the frightening reaction he give is very exaggerated, he is not even a minor villain but the protagonist best friend, so no one is after his life so reacting as if his death is already a confirmed fact when all he needs is just to live away from the main characters or just cut his relationship with the protagonist to free himself from the feet threads that connect him with the growth of the protagonist and the world will find another way to take care of the protagonist. The other point is the system, it's just hard to balance the novel if you add a system, even in The little tyrant, the author there minimized the usage of the system to a development tool for the territory of the protagonist in the background and I guess that he was thinking that if he utilised the system to it is full capacity then the novel will lose all of its value. In short, be careful of what you want and don't blindly mix the ideas and concepts you have in your mind and hope they will work somehow.
