The plot is too fast and rushed, making the mc development not optimal. Besides, if the story focuses on world travel instead of hi3, it's better to make the home world in a romcom world or a casual world, because hi3 already has a thick plot.
Arata_San:Thank you for pointing out the weaknesses in my novel. Now, it's clear what I need to pay attention to and improve to make my novel better than before. Although, to be honest, I feel a bit sad and disappointed seeing your low rating :v but anyway, thanks for the advice.
