I'm so tired of this "I think the manga will have a sad ending" bullshit. The author spoiled us of the end already with chapter XXX (140.5) and those morons keep this "sad ending shit" everywhere.

As stated by @johnpoop2529 she said that in the anime and I looked for this part in the manga and she also said that.
