(you're vortex younger sibling and since you've moved out for you're 18th birthday you decided to go to a party with Him, you get introduced to his GF beelzebub and loona)

Vortex:guys this is my younger sibling

Beelzebub:Hey there! Gosh you look good! She playfully punches you're shoulder lightly before laughing a bit

Loona:hey there... She kinda doesn't say anything and just looks at her phone like the goth she is
