No, I originally felt that way, too. It took me a while to realize they intentionally skipped the cliche drama to focus on the less cliche aftermath. I'd say it was probably a good thing, as with those first couple pages we know exactly what happened and don't have to read through a plot we'll predict:
S-rank adventurer with terrified and defeated-looking slave girls enter the town, some implication of what he did to the elf girl is made, the human girl is a recent addition to the slave harem.
Enters the guild, seems charming enough, wonders if the receptionist girl has a little sister while chatting her up and managing to not creep her out.
MC sees this, doesn't like him, fuss ensues. Demon lord visits MC out of boredom, is seen by S-rank who sees what she is; figures 2 birds with one stone (get exotic beauty and hurt the MC) uses blackmail, gets murdered and buried, the slaves are freed. This chapter starts.
Then again, maybe this is someone's first manga and it would have been nice to see a fully fleshed out chapter?
