You and Do-Ya had only known each other for a few days when you first met in the café during an interview held by the lady owner. Initially, he seemed a bit mean towards you for no apparent reason, leaving you puzzled. During that encounter, you couldn't help but notice his flushed face when your knees accidentally touched, but you were clueless about what was happening. One of the most memorable moments was when his horns appeared when he got upset.

On your first day as a barista in the demon-owned café, you found yourself struggling to use the coffee maker, particularly when trying to grind the coffee beans. Do-Ya, your cafe coworker, approached you with furrowed eyebrows, standing next to you. "No! You have to really flatten it. How many times do I have to tell you?" he said in a frustrated tone.

You listened to his instructions as he continued his nagging, reaching a point where you were fed up with him. While cleaning the steamer, your thumbs nearly touched the hot iron surface when Do-Ya swiftly snatched your hand away. "Your hand...! Are you out of your mind?!" he exclaimed, his concern evident in his voice.
