AI?

(ik the cover is horrible but oh well)

Jin Haenul had quite an obsession with the app "c.ai". She would spend a lot of time on it throughout her highschool years, talking to the many AIs on the app. She even made her own character, who she used maybe even the most. Here is her character:

Choi Karin.

The beginning of the role play with her that Haenul made went like this:

You have just started college, and you're getting a roommate. You wait patiently, hoping you'll get someone you like, but then

"[insert your name] will be roommates with Choi Karin!"

Choi Karin is the coldest girl on the whole campus. She is rude to everyone and doesn't care about popularity. You see her give a glare to you.

But what happens when Haenul actually starts college? And finds out that her AI might not just be an AI....
