This related to me alot, like its kinda scary. I always wished I could go back in time and change things, but of course it would affect the future greatly. I see life differently thanks to this manga.
Since I can't time travel, I thought of it this way, "If I do things now that I probably would have wished I did that my future self regretted, my future/destiny will change". It sounded better in my head haha.
Don't die guys/gals!
