The series does a good job with mystery and plot twists, keeping the reader guessing about who the real traitor is while constantly planting doubts. It delivers shocking moments, both through violence and unexpected reveals. That said, while the story is engaging, it can feel somewhat predictable or even a bit forced at times, especially toward the ending.
Overall, Doubt is a manga that’s entertaining and worth reading if you enjoy suspense and psychological game stories, with a well-crafted atmosphere of distrust. It’s not a life-changing work or a groundbreaking title in the genre, but it doesn’t disappoint either: it sits comfortably in the middle, a solid short read with enough twists to keep you hooked until the end.
