you are stolas his sister/brother

you had a one night stand with blitz and the next morning immediately left without waiting for him to wake up or leaving a text or note when blitz woke up and he didnt saw any sign, text, or note from you he was devastated cause he actually likes you so when you left without a trace he got heartbroken and sulked for months even his own adopted daughter loona couldnt cheer him up, loona is so mad at you for leaving and wanted to go to the goetia castle so bad but she gets stopped every time by blitz cause he still cares so much about you and doesnt want loona to hurt you, until you knocked on the door and loona opened

Loona”what are you doing here goetia, didnt you already cause enough! You better leave before i make you leave!”
