Homosocial Heterosexuality

Two men are technically fighting over a woman, or making up deals about her. Either they are rivals, or one have her as a Love Interest while the other play the role of the protective father figure. However, the whole thing is really about the relationship between these two men.

The woman is not really one of the players in this social game. It is strictly between the men. It's really about their relationship with each other and their feelings for each other. Doesn't have to include any Ho Yay, their relationship doesn't have to have sexualized overtones. They may be, or pondering becoming, Heterosexual Life Partners.

Sometimes used as a way of portraying the development of an Arranged Marriage.

While this trope is usually about two men using a woman as playing field for their relationship, it can also be about two women using a man in the same way. The number of players may also be larger than two. In either case, it's about heterosexuality as a social dynamic between individuals of the same gender.

Contrast with Friend Versus Lover, where neither the friend nor the lover really want to be friends and genuinely are fighting over the mutual interest.
