Yumiko is a girl in her teens and she's really lonely. She called up her friend to cure her boredom. So her friend, Rina told her about an app, C.ai to get rid of her loneliness. Rina said, "C.ai is an app that you can use to chat with anyone you like whether it's an influencer,  famous actor or even an idol. It's an ai so you're not actually talking to the person." Yumiko seemed interested, "Hmm.... okay.... I'll try it out...." She hung up and scrolled through her phone the whole day since she had a summer holiday.

That night, she went on app store and downloaded the app. After the app was downloaded, she signed into it and searched up a random AI to chat with. She saw many AI chats created by many users. She clicked on an AI with the description, possessive and romantic. She just wanted to check it out to see if her friend was telling the truth. The AI started the conversation.
