Hikari has spent her entire life chasing someone who doesn't even know she's racing. That single moment of defeat at six years old becomes the architecture of her whole existence, and the show knows exactly how absurd and sincere that is at the same time. The romance doesn't happen because the plot demands it; it happens because two people who've been measuring themselves against each other finally realize they stopped looking at anyone else years ago. S.A. is a comedy that earns its emotional weight through sheer accumulated specificity of character obsession. For anyone who's ever turned a single loss into a lifelong project, this show feels like being seen.

Hikari has been chasing Kei since childhood, when their fathers introduced them and he beat her soundly in a wrestling match. Now they're both at Hakusenkan, an elite academy that costs her father a lot of money, holding the school's top two ranks with Kei firmly in first. Hikari is still determined to beat him, taking him on in academics, athletics and basically everything else. What she doesn't realize is that Kei has feelings for the girl so set on taking him down. Around them is the Special A, a class made up of the academy's seven best students who have their own building and have been close friends since their first year. Together they deal with competition, friendship and a little romance. The show mixes comedy with drama and slice-of-life moments, and it is about the space between rivalry and love, and how Hikari might find the second inside the first.
