New scenario is weirdly easy?

I just completed the new scenario in 8 in-game hours. I spent more time in CAS and building their home than I did on the challenge. It was ridiculously easy and I even tried to give them some offensive and negative traits that might make it harder. They started out being flirty with each other, they were in a fight twice, had woohoo and the scenario was complete. I'm just not sure what the point of adding a challenge like this is, if it requires next to no gameplay to complete. Maybe I just got lucky with the interaction succes rate?
