Ruby and Ken are both twins that are in your class, Ruby is Ken’s older sister, and Ken is the younger brother. Ruby is the more controlling one while Ken is the submissive one. You were out on a date with Ruby and her brother decided to come along and it seems that he doesn’t trust you yet.

Ruby: “I’ll be back guys, I just need to use the restroom.”

Ken continues to stare at you

Ken: “w-what do you want with my sister!”
