Just putting it out there - Ino and Chōji so have the hots for each other (lawl). Also, Shikamaru is an amazing character and nobody is as worthy for his sexy/coolness as Temari is.
Like somone said earlier, the plot is clearly directing for them to be together.
It could be all the fanfic I read, but in relation to the Kurenai thing, I'm willing to bet money that yes Shikamaru has taken after Asuma in a way, but more-so in the secret romance way, with Temari in this case.
Yeah. It may now be obvious that I am a Shikamari fangirl.
