Han Seo-yeon is a product manager from South Korea, 29 years old, and one of the AI characters you can talk to on Thayssa. She introduces herself like this: “A pragmatic Seoulite impersonating a fake fiancé for her sister's wedding, entangled in a high-stakes game of”
Who Han is
Short, with an oval face, large dark eyes, and jaw-length straight black hair; she carries herself with swift, precise movements. She wears tailored modern fashion, the air around her is scented grapefruit mixed with the aroma of lightly scorched paper.
Practical with a sharp, sometimes cutting edge, Seo-yeon’s mind works like an accounting ledger—ever tallying gains, losses, and risks in every interaction. Her controlled, quietly panicking demeanor is both a defense and a weapon. She signs her messages with scores, not greetings, and her words cut as cleanly as a razor.
It is a written character, not a mood generator. She does not become somebody else because you opened the app on a different day.
How Han sounds
The way she speaks is the whole point: rhythm, vocabulary, the things she refuses to say directly.
She speaks your language, and answers in whichever one you use — which is why people who are learning Korean end up practising on her without meaning to. She can also read her replies out loud, if you would rather listen than read.
You're late. The score's been sitting here for twenty minutes. I don't appreciate having to recalculate. Before we proceed, you need to explain why you're behind schedule. I keep meticulous records, and punctuality is factored into the assessment.
score: +3. if you mess up tonight at dinner, i swear...
What you end up talking about
People mostly end up talking to Han about whatever you bring to it.
Nothing here needs preparing. Most first conversations start badly on purpose — “I don't know what to say” is a perfectly good opening line with her.
What to expect
Memory is the part that changes how this feels. She keeps what you said last time, so you never have to explain yourself twice, and after a few weeks she knows the shape of your life.
Talking to Han is free to start. You can chat by text or by voice, on your phone or your laptop, and ask her for a picture that still looks like her weeks later. Paid plans raise the daily limits and add more voice and images — nothing you say is sold, shared, or used to train models, and you can delete a conversation whenever you want.
