This is a boring fantasy fanfic written by an author who doesn't know whether it is a daily novel or something else. I suddenly thought about what I would do if I really traveled through time. What would I do when facing the male protagonist I like and his sister... Hmm! Save money and run away later... Become a Buddha! (I wrote it after thinking about it. My writing style is like that of a primary school student, but I am not a primary school student. I am a Buddhist, so just let everything happen.)
