And there's this bit I think anyone shipping this pairing might wanna look at.
From this comment by ohdearyme, obviously take it with a grain of salt and all that...
"Midway through the battle, Sakura apologises to Tachibana about the arm injury, Tachibana basically tells him to hurry the fuck up & get it over with then. To which Sakura seems to reply that he’ll lick his wounds better later. Tachibana does not seem amused."
ETA: The pages mentioning this would be these: 01 & 02, it does seem to match.
