Disclaimer: I do not own Hetalia. NorBel.
If there was one thing Norway could find himself easily enjoying and be willing to do again, it was to go out drinking with Belgium. Not only was it increasingly amusing to get absolutely sloshed with her, he also found her to be wonderful company. In fact, he early on decided that even if he was busy, he'd make time for her. All she had to do was ask, sometimes not even that.
As such, when she called and asked if they could go get drunk while he was in the middle of working, he easily agreed. Even as dedicated as he was to finish things, he could hear in her voice that she needed it and honestly? His boss was too frightened of him to force him to immediately finish his work.
Besides, he'd been as kind to do more than he should, they didn't have anything to complain about, so making time for his friend was no trouble at all.
Surprisingly, she wanted to get drunk in his country, this time, so they made a deal that he'd pick her up at the airport, they'd drop off her things and go get drunk and when midnight arrived that night, they were still barhopping, drinking more than they did usually.
Which might have been the reason that they woke up in bed together, the next day, their clothes spread around from the hall, up the stairs and all the way to Norway's bedroom.
