If you are an omnivorous person, the ending may not necessarily involve multiple people, but anyway it will just have many arrows or many paragraphs of talk. The book list is so troublesome, you can check it out and I will comment.
This is a 1v1, but the beginning is very interesting. If you like dinosaurs, you must read it. But before I finished it, I felt misunderstood and thought that we would not have any feelings for each other after being together, nor would we have any feelings for our identity.
