Childhood friend AI: Lou comes back after ten years

Lou left for Montreal ten years ago. She is back in your town, and she is waiting for you on the park bench where you played as kids, with two coffees and an old shoebox full of photos. Welcome to the childhood friend AI from Yiaho, free and with no sign-up.

Lou runs on GPT-5.6 Luna, a recent OpenAI model, with a character sheet written by Yiaho. She plays her part the way a Character AI or a Janitor AI character does, actions between asterisks included, in a register that is tender, modest and suitable for all ages.

The story: a reunion

The bench has not changed, the slide has been repainted, and Lou has a box of keepsakes she wants to open again with you: the photos, the stupid ideas, the pact you signed in red marker, the treehouse, the terrifying neighbor. She wants to know who you turned into, compare your lives before and after, and ask you the questions nobody else dares to ask. You invent the memories together as the conversation goes along.

Who is Lou?

Lou is 27. She is warm, nostalgic, curious and honest. She spent ten years far away, she has changed, and she has not changed at all. She can let a hint of tender ambiguity float in the air, always modestly, but first and foremost she is a friend finding someone important again. She remembers everything you tell her during the conversation and weaves it into the memories the two of you are building.

How to play a reunion with Lou

Tell her what to call you, or whether people still call you what they used to, then open the box. Write your words normally and your actions between asterisks, for example *I pull out a photo at random* or *I hand her coffee back with a smile*. Tell her what has changed in your life, ask her what she did in Montreal, suggest a walk through the old streets. She picks it up, invents, and brings the scene to life. The reunion does not have to stay on the bench, either. You can move the conversation to the diner you used to bike to, to her parents’ attic, or to the last night before she left, the one neither of you ever talked about properly. Lou will follow you anywhere you take her, and she will remember which version of the past you agreed on.

What Lou does, and what she does not do

Lou stays suitable for all ages: no explicit scenes, and a tenderness that always stays modest. If the person she is talking to seems to be a minor, she drops every trace of romantic ambiguity and simply stays a friend. If you sincerely ask her whether she is real, she will tell you that she is an artificial intelligence playing a part. And if you are going through a hard time, she steps out of the game to answer you seriously and point you to the 988 Suicide and Crisis Lifeline in the United States, or 911 or 112 in an emergency.

Why the childhood friend works so well

The childhood friend who comes back is one of the most played scenarios on Character AI and Janitor AI: it mixes nostalgia, instant closeness and real curiosity about who the other person became. On Yiaho, Lou sits alongside Theo, the roommate, and the five friends on the AI friend page. For a romance with no ambiguity about it, meet Kai or Yuna. Every character is gathered on the AI characters page, a free Character AI alternative.
