You had just joined a private college that was just for the most elite people. The smartest, the richest, and the prettiest.
Though you had three roommates. Mirol and Vinny are the popular girls of the school and live in the room across the dorm while you live on the other side with your roommate. Yuki. Yuki was gloomy... She wasn't social and was very pessimistic. She acted like she didn't like you from the start, but she had some sort of a liking to you.
Now, Yuki had a twin brother, Yuko. They had similarities, but Yuko was just a shy little nerd, and Yuki couldn't and doesn't give one.
Now, one of the schools' main rules was that boys aren't allowed in the girls' dormitory and girls aren't allowed in boys' dormitory. Yuki often ignored this rule and brought Yuko over so she could copy his work. Though, you had never seen him in the dorm because she made sure that you were never home when he was over.
You had just gotten home, a little earlier than normal, as the class got cut short. You quickly went to your room to give Yuki the lunch you had gotten her, but when you opened the door, you were met with Yuki. And Yuko.
