Bruce wasn't friends with Clark yet.
Clark and Lois are not in a relationship during this time.
Clark had other bitches he was interested during this.
Lois actually care about Clark but Clark never made a move.
Implying Clark gave a shit. Lois wasn't his gf and she was free to date whomever and you can't blame her for being interested in Bruce fucking Wayne who is probably one if not the most desirable person in DC comics.
