If you are baffled by Gunwook's position, let me remind you he stayed on top 15 the whole show while being hated by both korean and international fans, being evil edited and his only friends (possible alliances) being his direct competition. That means he wasn't anyone's filler and still kept going up. Some of the other trainees? Fillers, token even. Gunwook was always within the top 9 of every mock korean 1 pick, always on the top of Japanese 1 pick, if you cared for him and saw how his fans were moving, you would know him debuting, specially in top5, was to be expected.
