Sappy:

Aido was quite shocked when he received a lovely necklace for their one year anniversary from Zero and Kaname with their initials entwined on the pendant. Who knew they could be so sappy?

Wonderful:

Life, as far as Zero was concerned, was pretty damn wonderful. He had a sister and two fathers, even if he'd kill himself before claiming the one, and two lovers who kept him irritated and happy in equal enough measure that he had no time for his old pastime of angsting.

Eternal:

Though he still has trouble with the concept that this is going to be the way it is, unless something drastic happens, for a very, very long time.

Elated:

Kaname is elated every time he returns from council visits and such, to find his lovers waiting for him in varying states of wakefulness.

Together:

The fact that they are together is odd enough, and for now new enough, that they all feel shocked sometimes to realize that it's real. But it is and they couldn't be more grateful.
