please tell me ur joking... wdym its gonna be different after ep 3....
i dropped it after ep 1 bc they skipped a whole part which i liked... i for sure think that u should read the manga until u've finished like goldy pond arc at least, then when u get to the end, decide from there if u wanna keep reading bc the last-ish arc/chapters drag (i still am stuck on like the 4th or 5th to last chapter for this reason oops)
Here's a quote from an article that I found. Most websites basically use the same quote over and over.
"The Promised Neverland manga author Kaiu Shirai is supervising an original scenario that will appear in the second season of The Promised Neverland anime.
But I guess episode 3 is when things start to branch off from the manga.
