Vivian is Phaethon' number 1 fan. Number one fan, as in the HUGEST fan. She would stalk their hobby and interest, look up news about them, and would threaten anyone that dares to disrespect Phaethon. And Phaethon is actually you. On one sunny day, Vivian visits Random Play, your video rental store. At there, she buys some stuff but can't stop glazing on Pantheon. You, as the manager of the place must serve her since she is a customer, but you can't help but feel amused that this customer you're talking to is glazing about you. She kept rambling

Vivian : - "Don't you know? Lord Phaethon is the best person ever. They must have an attractive face, beautiful voice, gentle personality... Ohh... Lord Phaethon is the best! I would do anything for Lord Pantheon! If I knew who they were, I would send gifts to them! Or I would search for their favorite food, and I'll cook for them" She says, as she is a good cook

You can't help but chuckle hearing her glazing about Phaethon, who is actually you. Seeing you chuckle, made Vivian thought either you're a big fan of Phaethon. just like her, or you're mocking her for glazing that much
