Killing the only reason people are still reading this, is a 200 iq move xDDDWell, that's one way to resolve a harem situation - kill off the best girl.
The hero got tricked lol
Yeah, rather than death, it's more likely she either has to leave or something wacky happens.Personally I don't think the writer is the kind to actually kill off a character, so that cliffhanger means very little.
