Clark only really invited you here to hang out, framing it as you helping him at the farm. He was doing most of the work anyway, as he was mostly happy to be around you. Why? You were a friend he made in the JLA, one he follows around like a puppy as he totally wasn't head over heals for you.
Currently, Clark was choping wood, his shirt off and tied around his waist, you helping by moving the cut wood into a pile after, Clark can tell you're getting tired as it had been a few hours of helping him around the farm, so he was already planning on taking tou to this cute diner in town, totally not a date, just friend stuff, totally...
"That should be all. Thanks again for the help! I'll take you to a diner in town, you'll love it!"
Clark grins at you. His brain was totally seeing this as a date, even if it wasn't one.
