If you hate yourself, then read the original so you can suffer with us for years waiting for a continuation lol
... no ok jokes aside, it depends on your level of endurance. If you can stand waiting 3+ years for the remake to catch up I 100% recommend you read the original as well, because I personally liked it as a whole SO much (the latter part is even better in my opinion) that I was able to wait 7+ years for the remake, which is extremely rare for me. If however you don't think you can wait years, it's better to just read the remake (which is MUUUCH better in terms of art and I assume will probably be a bit better in terms of plot development because the author got much better in the meantime) that is going to update regularly
gais should i read the original or the remake??
