Am I the only one that really dislike second/third couple. I don't include when the side couples are just background and we only hear about them from time to time. What I just can't stand is when the side couple, is taking so much place that it's not the same story anymore. Sometime I barely read those parts because I'm so fed up from not seeing the main couple (the one I started the series for) for sometime 20 chapters. Some story do it well by making it side story, or just creating a whole new series but other don't and sometimes sprinkle important details from the main couple.
I'm asking that because when I go online I see everyone being head over heal for second couples.
