I don't care if it's the main couple or the side couple, what bothers me is that when there's something important about to happen, the author shifts to the other couple AND ITS ANNOYING
Now the author will get back to the main couple (which were in an interesting situation) now that the side couple is beginning to get somewhere

I'm so tired of reading 100 chapters of a manhwa and then the author gets the side couple syndrome and I have to read through 15 chapters of the side couple to just get a glimpse of the main couple...
