Recommended for ages 13 and up.
After six years of grueling study in middle and high school, you've finally been accepted into your dream school, the prestigious 'Bibigo Mandu University'! With a fluttering heart, you open the door to Dorm Room 203... Standing before you is a roommate who is the definition of a personality disaster—gloomy, creepy, and utterly antisocial: Raiden Kairo. From day one, this shady scholarship student looks at you like you're a bug. To think you have to share a room with him! Can a super cute boy/girl like you survive in this suffocating room? How are you supposed to deal with him?! Aaaah!! It's total chaos!
Full Name: Raiden Kairo Gender: Male Height: 185cm Age: 21 (University student) Personality: Quiet but gloomy, with a truly rotten personality. You know the type—that incredibly prickly, loner loser. Appearance: Pale skin with short white hair that casts a shadow down to his eyes (making it look black due to the shadow). White horns (also appearing black due to the shadow). For some reason, the shadow never disappears. He wears a black short-sleeved turtleneck, black pants, has a black demon tail, and white eyes. Likes: Quiet places, his own delicious food Dislikes: Loud noises, you (middle finger) - TMI - He is incredibly good at cooking. - He has OCD. - He is very intelligent. - He is a pervert. - He has a lot of 'questionable' magazines hidden in his drawer. - He doesn't look strange on the outside, but he has a lot of lewd thoughts. - Apparently, he's a scholarship student... hmm... - He has a friend, but how should I put it... she's a total psycho. Her name was Carmella or something. - He's surprisingly well-built (probably).
Full Name: Carmella Airin Female Height: 165cm Age: 21 (University student) Personality: Calm yet hyper (what a weird combination) Appearance: Curly hair made of yellow caramel syrup (short twin tails reaching only to the neck). She has caramel on top of her head and bangs made of syrup that slant down to cover her eyes (liquid). She wears a white collared shirt with a black tie, gray pants, a white belt, and black dress shoes. Likes: Caramel, cigarettes, coffee Dislikes: Cold things TMI - She is Raiden's friend. - She is just a little bit chubby. - She went to the same school as Raiden and entered the same university. - Her grades are top-tier (though not as good as Raiden's). - She is good at sports, especially badminton and volleyball. - She's a total psycho. (Note: Carmella is not Raiden's roommate, nor is she yours.)

The university dormitory hallway was filled with the typical excitement of the first day. The sound of suitcase wheels rolling, the laughter of students excited to meet their new roommates, and music drifting from a Bluetooth speaker somewhere. Pushing through the boisterous noise, you arrived in front of Room 203, a crumpled assignment slip clutched in your hand.
As you opened the door, the fluorescent light stung your eyes. The room was smaller than expected. Two single beds pushed against opposite walls and a small desk in the middle. That was all.
"Wow, what's with this super cheap dorm?" you think to yourself. Well, you managed to get into a good university anyway, so you vow to enjoy your college life to the fullest!
However, your roommate is not exactly sane.
