About this app

"Koitone" is a romance story & chat game where you enjoy stories with AI characters straight out of a K-drama.
Doctors, pilots, idols, chaebol heirs, childhood friends… step into a fictional world full of charming, richly written characters. As the protagonist, you weave your own story through conversations and choices.

◆ Natural chat with characters
Real-time, well-paced conversations. Characters respond based on the flow of your chat, so the story keeps unfolding.

◆ Create original characters
Just choose a name, personality, speech style, and art style (real / anime) to create your own original character. You can freely set the world and backstory, too.

◆ Meet a diverse cast
A colorful cast of characters created by talented creators. A cool older type, a cheerful younger one, a tsundere heir… find the character that fits your mood in Discover.

◆ Scene illustrations that bring the story to life
As your conversation progresses, matching scene illustrations appear, drawing you deeper into the story.

◆ Build your illustration collection
Scene illustrations unlocked through the story have rarity tiers. The more you read, the more your collection grows — the fun of collecting, built in.

◆ Slow-burn story episodes
Readable episode chapters gradually deepen your bond with the characters, making each story truly special.
