This is the radiodust comic from Rinnax3. She's the artist.

Alastor has always had trouble with emotions. Since Alastor has moved to the Hazbin Hotel, he's felt all of these new and strange emotions he doesn't understand, and he always seems to feel them whenever Angel Dust is around, or whenever Angel Dust crosses Alastor's thoughts. When seeking advice from multiple friends, they tell him that it sounds like he's experiencing jealousy, fluster, confusion, embarrassment, and love. Of course Alastor thinks their all crazy, right? Alastor didn't love Angel Dust! Wait....no one asked if Alastor loved Angel Dust.
