Temari broadly smiled at Shikamaru after she defeated Tayuya.[1]
Despite her usual tough demeanor, Temari has a tendency to show a softer nature around Shikamaru.
Temari showed concern for Shikamaru when they were at hospital after he failed his mission.[2]
Shikamaru and Temari were specifically reintroduced together at the beggining of Naruto Shippūden.[3]
Naruto thought Shikamaru and Temari were on a date[4], a scene very similar to another one where Kakashi thought Asuma and Kurenai were on a date.[5]
Temari thinks highly of Shikamaru's intelligence, to the point she believed he would be a good Hokage.[6]
While complaining to his father about how much he hated women, Shikaku told Shikamaru that even the roughest women is tender to the man she loves, leading Shikamaru to think about how his father is always bossed around by his mother.[7]
Later, after she rescues him from Tayuya, Shikamaru thinks that Temari is scarier than his own mother, indirectly equating his relationship with Temari to Shikaku's relationship with Yoshino. [8]
Shikamaru was shown dreaming of Temari standing by his side in the Infinite Tsukuyomi.[9]
It is revealed in the final chapter that Shikamaru and Temari are married and have a son named Shikadai Nara.[10]
