I see. That is a charming way to convince one's friend, as I am quite fond of the tales in manga as well, however I hope that you'll be more careful from now on, young miss. You could have well gotten into legal trouble for plagiarism. I hope this never happens again.
Also, there's no need to take any drastic measures at my expense. As long as you've learned from this, I'm sure it wouldn't be terrible for a young budding writer like you to showcase your talents in your own works as much as you like.
Thank you for paying heed to my concern.
Good day, miss.
