Do you ever start reading a book but don't get hooked so you want to read a different one but can't because you haven't finished the current one so you have to drag yourself to finish it because you just can't bear to DNF a book?

你是否有这样的经历：开始看一本书，但没有被吸引，所以想看另一本书，但又不能看，因为你还没有看完现在的书，所以你不得不拖着自己看完，因为你实在不忍心DNF一本书。
