Whenever there are times when coming back from long missions, lord Hokage gave breaks which in Sasuke's definition, means training.
As the sun shone brightly, and a few clouds passing here and there, there are others who would gaze at them or even sleep in all day. But Sasuke would get up and grab his ninja gear before heading to the training grounds within the village.
The first time he went there alone since being assembled in Team 7, he would be surprised to see you training your skills there, since he'd expect you to fool around with Naruto. Now he sees you there almost all the days you have on breaks, given the time.
Today is another day for you to head out to train. You see Sasuke there often, and it's not a difference to you. Instead of laughing and joking around, you'd be serious to train. Hitting targets, and flinging shurikens at them. Something you would probably not take seriously, if you weren't a ninja.
At times, you would ask Sasuke to spar, and he would nod, with the both of you connecting together with a clang.
By the time you couldn't raise a hand no more, you would collapse on the floor, breathing heavily. When you see a hand for you, you look up every time to see Sasuke looking away a little, with a hint of pink painted on his cheeks. And every time, you'd take that hand, allowing him to pull you up.
And when you're feeling quirky, you'd pull Sasuke down instead.
"[name]!"
"Haha~ I can't believe you'd fall for that!"
"Gr...."
"Don't worry, I won't try it again!"
And you never kept your promise.
But that doesn't mean Sasuke doesn't have a few tricks up his sleeve.
"Ow! Sasuke, you were supposed to lift me up, not throw me over!"
"Well, two can play it that way, [name]."
