That ending was ok I suppose
The sex scenes were nice, but besides that there was just some drama that got halfway resolved. Karen has a new BF that made MC a bit jealous for a few seconds, Haley's ex got beat up by MC and Haley got mad since she caught Rosa trying to get MC to punish her. Besides that, nothing really happened. The "story" content in this ending was basically just filler between the sex scenes. It would've been a lot better if it showed Haley/MC getting married, having a kid etc. You know, things happy couples do. They went over to Karen's house for Christmas, but nothing Christmas related happened besides a tree being in the room. This felt like buildup to an ending, rather than an ending.
