I really like your game. But I think stuck in the "whore" ending of worker (;へ:)
How could I get it? I've stolen 4 time his panties and get 1 strike.
To get the construction worker to hate you you have to steal underwears 3+ times before the first fuck. After that, he'll hate you and you'll arrive at the Whore Ending just by playing naturally.
It looks like you're still stuck on the love path. I suggest you restart from the beginning and remember to steal underwear 3+ times before the first fuck with him.
