I'm sure all of you have had this dilemma at some point. You watch something that is amazing. You then find yourself searching for info on newer season of it - only to end up waiting what could be years for it (and you just never know - you could get your wish. It does happen). Or... you end up a heartbroken soul when you confirm a new season is never going to happen.
Without spoiling anything please, what anime have you come across that did that to you?
