@Nick86 Let's just say it as "first-girl-win" cliche which people don't favor too much (since it's predictable). I personally don't have problems with it as SS is written well enough for that, but everyone's opinions differ
Well, it was definitely rushed and open-ended, but at least this way doujin fans can create their own idealized ending off the manga instead of the LN. I thought it was fitting.
@ZexahVEVO: Aika and MC got together. The LN actually wasn't bad, but people are pissed because of the "first-girl wins" cliche.
(The following is just my opinion. Take it with a grain of salt!)
Personally speaking, people seem to want to ruin manga for themselves by concluding who ends up with who and if it falls in a "cliche," then it automatically becomes crap to them; the "first-girl wins" one is an especially sore spot with some people. I've always believed in the saying "It's cliche because it works." That being said, there is such thing as too much cliche in one story. I don't believe this does that; I think it (and the LN) had a nice balance of cliche and unique story.
But that's just my viewpoint. I don't speak for anyone else.
