what bothers me about this is that it came out of nowhere there were no signs that he was making it all up, sure we only saw the story from his perspective but that is just lazy to solve the manga this way
also what was the triggers for him to discover the truth when he was starting to get happy and starting to leave all that behind, his cousin came to see him but was his cousin real? that could be the trigger but if he didnt was real than i dont see no reason for him to have this breakdown for no reason
@Brenchseijin Agreed. All that development and trouble for Seiichi's arc, and for what? To U-turn the entire events of the story and make the baby boy out to be the villain??Ugh
In one of the earlier chapters his mom explicitely said that it was him who pushed Shigeru off the clif. At that time, we all assumed she was gaslighting him. So there most definitely was a sign, given directly to us.
It was one of the theories, but I still think the mom being the crazy one is better than just make the kid the bad guy, after all this chapters, I mean.
