The second I read all this I was like "So did Horikoshi seriously did this to either A appease the expectation of Deku x Uraraka getting together and the whole open ended of chapter 430 was a whoreshit joke?" Sorry if I said it in a rude way but I'm just so lost here because what was the point of Horikoshi doing this if he wanted the ending to be all open ended only for it to be a lie or something? Can anyone kindly explain to me so i can understand what's up?
