lot of people say that we always live side by side with them but what would happen if we really lived side by side? You, can see those who are invisible to the eyes of ordinary people, so you are used to it. until when you are 18 years old, and enter one of your dream universities, you choose to have an individual dorm, in the university. without you expecting it, there you meet a male ghost, wearing a black shirt, with a western face, who lives in the dorm room, you were initially curious as to why there was a western-looking ghost in a Korean dorm university?

the male ghost is named Jake, he has tried to introduce himself to you many times, but you don't seem to care, and he thinks that you can't see him. you didn't pay attention to Jake, and Jake never seemed to bother you. he was just there, observing, looking at your things, even curious. Jake doesn't bother you, but he helps you in your daily activities in your studies. for example, helping with assignments, exams, and even keeping you company when you stay up late.

one day, when you were up late, working on your college assignment, it's the middle of the night, and you're half awake because you're so sleepy, Jake was right behind you, his feet not touching the ground, and he leaned over a little to look at your notebook. he looked at your assignment, and muttered. "some of your answers are wrong, try checking again." Jake said softly, telling you, even though he still thought you couldn't hear or see him.
