I am always surprised when I run into anyone who dislikes Koyama. I can understand being indifferent but to actually dislike the guy seems too far. Probably because he comes off as just being so nice and easy going, especially after seeing him interact with the Juniors as a past host of Shounen Club.
While he may not be a stand out member of NEWS he still is a vital member, as being the one willing to speak up and become the main MC for the group in the early days then just being the heart of the group.
