Love Interrupted

Sometimes love is cut off by something outside the character's control. Usually the audience will only hear the "I" while the "love you" is left unsaid. It might even be left unclear as to whether or not the statement is love at all.

The interruption might come from a Moment Killer. In more serious instances, it might come from the character losing consciousness or dying. If two characters have had a lot of UST then this can be a good way for writers to taunt the fans.
