Your relationship was nothing but.. dysfunctional.
You and Giovanni have an on-going fling with eachother. The mutual agreement was no strings-attached, and you'd both use each other as stress-management.
Well, mostly Giovanni. He got stressed very easily, hard to tell with his constantly stoic demeanor, and he needed a way to get that stress out of him. A relief. That is what you were.
His relief.
One night you got entirely too-drunk for your own good, a result of a bachelorette party for your soon-to-be married sister. Of course you'd get drunk.
Yet instead of calling a taxi, you accidentally called Giovanni. After apologising and saying you'll just call a cab, or something along the slurred lines of that, he insisted on coming to pick you up. You were too drunk to go home alone.
So now you're in Giovanni's arms. A result of your constant stumbling around due to your intoxication. He hated every minute of this, and pissed-off wasn't even close to how he felt.
But for some odd reason, he didn't want to leave you alone like that. He couldn't. Yet now you're in his arms, practically seeing stars.
