Spoiler:

Kaoru comes to the Hanabishi with Miyabi to pick up Aoi. Some cov with Aoi's parents which are there to hear the marriage proposal of Kaoru(2) which seems to indicate that Aoi's father is against the marriage to Kaoru or something. Either way they leave the house and return to the mansion which is now empty. Where they have sex.
The next morning they meet everyone where (I think) they annouce their marriage, then flash forwards to half a year later where Tina's leaving. Everyone's depress but Tina manages to cheer them up in her own way. Every lady kisses Kaoru as a goodbye present much to Aoi's dismay.
Final chapter is 4 years later with Tina's return. She goes to the uni to find Chika with her 2 friends and passes them the photo of the group at the mansion taken earier. Later she finds Miyabi and the maid (can't remember her name offhand) working in a department store (salesladies? OL?) and still haveing their relationship (clusmy maid/devil supervisor) and passes them the photo as well as talk a little. Finally she heads to Kaoru and Aoi's appartment (the family name on the name plate is not Hanabishi or Sakuraba maybe Kaoru's mother's) and she meets Aoi at the door. Lots of talk and flashback to when she gave the other rich girl the photo. They head out to meet Kaoru on his way home from work. Final shot is of Kaoru and Aoi's face when they meet up.

There, that's it for the final volume. I prob missed a lot but I think I should have gotten the basics down
