One of the most popular pairings in the Naruto fandom due to its many hints both in the manga and anime. An example of a hint is in the beginning of Part 2 of the manga. Naruto sees Shikamaru with Temari and believes they are on a date. A similar scene happened earlier in the manga with Kakashi believing Asuma and Kurenai were on a date. Asuma and Kurenai were later married.

ShikaTema is a much better pairing than ShikaIno.
