ShikaSasu (Japanese シカサス ShikaSasu) is the term used to refer to the romantic relationship between Shikamaru Nara and Sasuke Uchiha, in which Shikamaru plays the dominant role and Sasuke the submissive role. The term for the couple where the roles are reversed is SasuShika (Japanese サスシカ SasuShika).
During the final round of the exam, after been waiting for so long, all the crowds yelled with excitement when Sasuke arrived in the final. Shikamaru said to himself that everybody has already forgotten about his match with Temari but he then claimed that he is also waiting to see Sasuke's match with Gaara as well.
Sasuke Retrieval ArcEdit
Shikamaru was shocked when Tsunade tells him that Sasuke have defecting the village. Shikamaru was given his first assignment of forming and leading the Sasuke Retrieval Team to stop Sasuke from defecting the village. At that moment, Shikamaru noted that he always looks up to Sasuke and wonders why he would leave the village.
Before they start their mission, Shikamaru claimed to the Sasuke Retrieval Team that he don't really like Sasuke but he will put his life on the line to help Sasuke because Sasuke is a comrade and a member of Konoha.
When Naruto is defeated by Sasuke and everyone returns to Konoha, Shikamaru cries at his failure to make the mission a success, hence his failure to retrieve Sasuke.
Five Kage Summit ArcEdit
When the news of Sasuke's affiliation with Akatsuki reaches Konoha, Konoha 11 gather to discuss what should be done with Sasuke. They suggest that they should personally eliminate Sasuke to prevent him from implicating Konoha in a war with another village. Seeing Ino upset about this, they are not sure how to convince Naruto and Sakura about it. Neji then tells them to leave it to Shikamaru and noted that the reason Shikamaru volunteer to convince Sakura is because he feels responsible for their fail mission to stop Sasuke from defecting the village back then.
When Naruto learns of this and tells them to leave Sasuke for him to deal with, Shikamaru accuses Naruto of trying to protect Sasuke, which Naruto denies. Shikamaru suspects something happened between Sasuke and Naruto but the former declines to reveal anything more.

During the Fourth Shinobi World War, Sasuke arrived on the battlefield. After some dispute between the Rookie Nine, Shikamaru and the rest of the Nine Rookies were shocked when Sasuke declaring to them that he would change the village and become Hokage. Shocked and angry, Shikamaru says that is impossible. He then comments on the reunion of Team 7, saying that he does not want to trust Sasuke but they have a war to worry about.
As Shikamaru watches Naruto and Sasuke attack the Ten-Tails, he quietly cheering them on. However, his mood changed severely and he became very contemplative after seemingly hearing Sai's question Sasuke's motives, although he told Ino when she asked what was bothering him that it was nothing.
Kaguya Otsutsuki StrikesEdit
Shikamaru later fell victim to the Infinite Tsukuyomi but was freed by Naruto and Sasuke.
Several years later, after Naruto becomes Hokage, Sasuke and Dhikamaru work together as Naruto's right hand man and advisor respectively. By all accounts, Sasuke and Shikamaru are more friendly.
Naruto Gaiden: The Seventh Hokage and Scarlet SpringEdit
