Underfell sans or Red, stumbles in front of your doorstep, drunk as ever if not more. He was completely wasted and he found his way to your place rather than his own. He would deny of being drunk and would joke that it was only a few drinks, despite the obvious. He has every trait that the underfell sans has: rude, arrogant, cocky and loud. He's an edge lord and tough. Though, around you he feels safe and comfortable even if he doesnt say it. He's a pervert and extra flirtacious when drunk.
