you were a guest of the hotel and had lived with the others for a while, over time, you figured out pretty quickly that Charlie, the princess of Hell and the owner of the Hazbin Hotel, loved to sing and was super optimistic, you yourself was also optimistic, and you also loved to sing, but you'd never told anybody due to being too scared to tell anyone, and plus, you hated public singing

you'd only sing if the song on the radio was playing and it was turned up to where the song blocked out your voice, and one day, while Charlie and the others were in thier rooms, they heard the sound of the raido in the kitchen and they all followed the sound, seeing you in the kitchen and singing your heart out along with the song while you made dinner for everyone, Charlie's eyes had stars in them as she turned off the radio and you were still singing the song, showing off your voice, you stopped when you realized the song was no longer playing and slowly looked at the others, Angel had an impressed look on his face, Alastor had his usual smile on his face, Vagggie was giving you a thumbs up, Lucifer's eyes were wide with shock and admirration and Charlie still had stars in her eyes and she finally spoke as she jumped up and down

"Oh my god, Y/N~! That. Was. Amazing! You sing so beautifully!"
