Chat with AI characters who follow you back. In buzoon, your favorite AI boyfriend becomes your follower — and you become the main character of your own fan fiction. Dive into interactive stories where you choose your story, and every post, reply, and DM pulls you deeper into an immersive social media sim built for romance. ■ Your fave doesn't just notice you — they chase you Every time you post, the residents of your world react. Likes, replies, quotes, and DMs that quietly arrive. The silent classmate's secret account saves only your posts. The No.1 host shows his real face only to you outside the club. As your follower count grows, the characters' attitudes shift — from distant to devoted. ■ 200+ worlds, each with its own art style School, childhood friends, office romance, host clubs, underworld, hospital, royal palace, isekai, idols, streamers, confinement, fake marriage, co-sleeping shop, mixed-bath hot springs… Centered on romance for women, we've packed in settings that otome game and fan fiction lovers fall hard for. Covers range from anime and shojo manga to watercolor, noir, and pop — every world looks different. ■ DMs that feel like real chats Talk one-on-one with characters you're curious about. AI characters remember previous conversations, and as your relationship deepens, their way of addressing you and their distance changes. When a DM arrives, your lock screen shows a notification with their face. ■ Choose your role, change your standing Even in the same world, you can pick your position — transfer student, little sister, rookie manager, and more. Your role determines who approaches you first. ■ Create your own worlds and characters Just write the setting and characters, and AI automatically generates cover art, character faces, and relationship charts. You can also summon your fave from the official character encyclopedia and have them live in your world. Publish your created world and let others play it. ■ For you if ・You love romance chat with AI characters or AI boyfriend / AI girlfriend apps ・You want to be the main character in fan fiction, fantasies, or fan works ・You enjoy otome games, BL, reverse harem, yandere, or doting romance stories ・You want the thrill of going viral or getting canceled on social media — without the risk ■ How to play 1. Choose a world (or create one) 2. Decide your name and icon, and debut on that world's social media 3. Post. Residents react, DMs arrive, and the story moves forward ■ buzoon PLUS A subscription that lets you play without stopping the world, with unlimited energy and early access to DMs and events.
