Why do good stories always have harem endings :(

If I were to make a guess its to "keep everyone happy" with the final partner, plus... lets be honest there are lots of degenerates and teenagers un the hobby so its not too surprising right?

Yes ikkkk but everytime I read books like this I get my hopes too high just for them to be shattered wtf. This has happened with sooooo many books now I’m too scared to click on a reincarnation or time travel book with a male on it
