I think this should help remedy Nick's issue.

One word: Tsundere.

After countless manga and anime, people have become conditioned to accept that the Tsundere, if introduced as a primary character, will always win. Even if it isn't 'true' Tsundere, just the fact that the character 'warms up' to the MC after initially treating him/her like dirt(even as a joke), is more than enough for people to instantly think "Well.... we know the end-girl now." People generally associate such characters with sadistic tendencies and likelihood of using their feet, which is all fetish and fan service. This is further exemplified when the 'second girl' is the complete opposite and fully supports the MC, because in many many cases, said girl eventually loses the run to the Tsundere simply because they lack the impact of the other.
