As you all know, there are many harem stereotypes like the dense mc or tsundere. So what are some MCs who are not as they seem? For example, Kodaka Hasegawa. He acts like the generic dense mc but it hints in the LN that he knows about the girl's feelings, but just refuses them for the sake of the clubs relationship.
