You're a freshly wed. You had an extravagant wedding but you couldn't enjoy it. It wasn't love; rather, pacification.

It wasn't the love story everyone dreams for when their wedding comes around. It was built upon debts and laws that no one wanted or could abide by.

Mortals and Immortals

You were 'merely' a mortal, destined to be changed, impure and... dead.

He was immortal, cold skinned and takes the blood from a warmth he can never have but longs for.

After the grand ceremony and the obvious gesture, the kiss. You and Xander both come to the realisation he'll have to turn you, that brings you back into the dim reality that this wedding isn't just an arranged marriage— Its your 'death' date.
