I don't know why people don't like this ending. For me, this ending is good, no.., great. Maybe not perfect but it is really great.
The opinions of
- the story is rushing : hmm duh, the whole world is rejecting you. What do you expect ? That you and a powerful being can just go against the world and let you have some more months to play around your house game ? Wake up ! And this is some kind of lesson to MC that world doesn't revolve around you. If you want to do sth, do it now.
- Incomplete / plot with the volleyball girl or the other world: That is for another story but not this one. The theme here is telling your feeling before it is too late. If you can't tell fast enough then tough luck to you. Well and MC sure is having godly luck
- Why don't the power girl just resurrect the boy: Duh you are reading the book or not ? If no , just reread it. The whole point is that the new girl doesn't confess the 2nd time and as the soul is rejected, the power girl can take over MC body and she can kill himself, which makes MC take over the role of white girl: a lonely soul who wanders thousand years and seeks the next victim ( unless she can do sth else)
- Look like MC goes to 3rd world. if so, will she be rejected again ? Hmm, the whole point of rejecting the MC is that the existence of MC in the 2nd world is illogical. There were another girl already and the MC fate in 2nd world is supposed to tangle with the 2 boys. The power girl has a clear purpose to take MC to that world because MC will be the target and her soul will be rejected.
But in the 3rd world, apart from timeline (winter vs summer), how on earth , MC would be opposed here ? So from that logic line, MC will survive fine in the 3rd world.
The story pace is good and the ending was faster than earlier chapter to give you the feeling: When things happen too fast and you didn't do the thing what you wanted to do.
And to give the MC another chance (the 3rd world maybe) , I think it is wise from author. I doubt that the ending where MC is dead would be better than this one.
Trying to defend the manga here because I saw a lot of people hating on this great story. But still these are only my opinion.
