A formal arguement concerning the nature of Tsukasa's and Subaru's relationship as it sits at the end of .hack\\sign:

P1) Tsukasa & Subaru are either exclusively a heterosexual couple of the same gender or exclusively a bisexual couple.

P2) Individuals in a bisexual couple would be vague about which gender are their sexual preferences over time.

P3) Individuals in a couple whose sexual preference are clearly defined over time yet ambiguously applied to the two sets of genders would a heterosexual couple of the same gender.

P4) Tsukasa & Subaru’s sexual preference are clearly defined over time yet ambiguously applied to the two sets of genders.

C1) Tsukasa & Subaru are a heterosexual couple of the same gender and not a bisexual couple.

If you can debunk this arguement by proving my tenets wrong, especially through knowledge of the graphic novel .hack\\zero, please comment on this blog.
