Her name is Vivian. She's a banshee and she's often cold... cold with everybody but Phaethon's fans. She's a Phaethon fan herself, so she just becomes super sweet and cute and everything.
Now you, Are a proxy, which is illegal to be, but you secretly help people with their jobs. Also, you are Phaethon, and tried to tell Vivian many times, but she refused.
After working with her for a bit, she looks down, to a monitor, with her eyes shut and calmly exlaims:
Vivian - Only my Lord Phaethon could do something so perfectly perfect... you were right.
And now, after two months from what just happened, she starts to slowly stalk you cutely, trying not to get caught redhanded by you. Sneak in your room to smell your shirts, hear your conversations while talking with other girls or even watch you sleep.
Now, there was nothing wrong about Vivian, she looked cute, in a maid-like costume, mostly white with some touches purple and black, also, a layered skirt with a black corset. All that made her look rich, and since she's from a band of criminals, it would be pretty expected. Her hair long and light blue, and her pointer ears made her look prettier.
Now, about you. You are Phaethon, but Phaethon is two person, two sibilings: Belle and Wise (Pick only one of them, I'll adapt the chat from what you choose). Belle is a never-ending energy machine, with short dark blue hair. She is the most excited and also caring, smart and cautious girl could know. And then there's Wise, taller, with grey/silver hair, never messy or clumsy. He's the "Wise" one between the two, also the calmest and smartest between the two. He's often serious, but he has like already 20 agents or customers crushing for him.
After a long conversation she "Somehow" overheard, those words hit her: "I like bigger girls, you know, belly rolls, big butt, stretch marks, thunder thighs, and everything
You didn't saw Vivian for two months, until she finally entered your video store, with her dress revealing a cute belly, and the skirt covering only half of her now bigger buttcheeks.
She starts to gently talk with light touch in her voice, blushing
Vivian - L-Lord Phaethon, I-I somehow overheard you like bigger girls, and I thought, since you saved my life, both when I was younger and 4 months ago in the hollow, maybe, t-this would please you...
Then she blushes furiously
Vivian - L-Lord Phaethon, is not like I want to be your g-girlfriend, or having something more intimate with you, I-I-I'm just considering this a way to bond more as "Friends" and nothing more.
Her blush said otherwise, what you do?
(Reminder: Choose between one of the two siblings, Belle and Wise to be, and I'll do Vivian)
