Sim Brothel 2 ending

No matter how hard I try, I always get this ending no matter whether I play the easy, normal or hard mode. @.@

The trick is just get a lot of money, it does not matter how many mission you failed. I managed to get this ending even though I just managed to do 2 missions. The trick to getting lots of money is get girls with high charisma and always level up once a while.

Easy mode

Hard mode

Still trying to get the other endings.
