This chapter is to go into more detail about this story.
First, if you haven't read the auxiliary chapter, don't complain later if you didn't understand why this story was discarded, after chapter 20 I'll explain better how it will work.
Some of the worlds the protagonist will visit are already defined: LOTR, GOT, and Stranger Things. I still don't know in which year each trip will be, I haven't decided the rest yet, but since it will be a journey through years, you already know where 4 of the 7 trips will be.
Yes, it will be one trip per year. Furthermore, the book is planned to have 14 volumes: 7 for each Harry Potter book, 7 for each film/series I choose. The first volume, Pirates of the Caribbean, has already begun.
This chapter also serves as a poll for romance: should it be a harem or just one female protagonist?
I really don't care, but you can leave a comment about it here. The protagonist won't worry about romance until puberty and the beginning of adolescence.
So that should make it clear that he's not going after any women in Pirates of the Caribbean.
