Nam Woohyun - 20 years old

          He is a graduate from Baek High two years ago, and already a music enthusiast since middle school when he was always brought to his father's vocal studio, and he succeeded applying in HyunStar Ent.. He is one of the honor students and a part of a popular performance group that rivalled another "group" tensely in the major events in his high school. That's when he got bullied and picked on by some though, and he was quite a sensitive person at that, so when he gets hurt, he "really" gets hurt (he hides it though). He also had an alerting condition back then that affected his vocals temporarily. He is cheerful and friendly, and he really does care a lot for "certain people". He gets a bit quiet and reserved when meeting new sets of people though, but tries to show his bright self still. He is competitive and pumped up at times though, and that had to do with his experience at high school. 

Kim Myungsoo - 20 years old

         He is one of the new producers and composers of HyunStar Ent., as he is related to the CEO in some way. He was the leader of the highly recognized "Infinitize" band in Baek High two years earlier, and that's where he had some difficulties, and he would blame it most to a competitive guy named Nam Woohyun, and there's those times that he won't forget, because he'll take "revenge", and it is actually gonna happen for them to meet again, and that was a surprise to him. Maybe the slightly cold, sneaky but actually affectionate and fun man has his "thoughts" already, but there could be more behind his outlook towards Nam Woohyun, and problems that he should deal with.

Lee Howon (Hoya) - 21 years old

        Along with Myungsoo, he was one of the first to work in HyunStar Ent., in which he is a dancer and choreographer. His dancing were highly praised when he auditioned for the job immediately. In his high school in Busan back then, he was rather deemed as an "ice" prince, since he's usually quiet and firm-looking (though hardworking and caring in some sort). A couple of students (both genders) confessed to him in various ways, and he was quick to reject them, since he wasn't into dating much and he has a blunt way of speaking sometimes, but what if there's someone who can actually make him smile more than he thought, and make him forget about his "icy" persona?

Kim Sunggyu - 22 years old

        He is one of Woohyun's dormmates (with his room between Sungyeol's and Woohyun's) when Woohyun moved to Seoul, and he was also from Baek High, and he is well known for being the leader of the Vocalists Club in 11th and 12th grade.  He is the head vocal instructor of HyunStar Ent., and close with Woohyun and Sungyeol also. He is protective despite his firm nature at times, but he's open and had to do with being a "representative parent" to the employees and enrollees, especially most of them are younger than him. (Almost all employees are really young)

  Lee Sungjong - 18 y.o. -  Myungsoo's younger cousin who casually visits Myungsoo's workplace occasionally. Can get hyper at times, but nevertheless, he will behave well especially with Myungsoo around him.

 Lee Sungyeol - 20 y.o. - Woohyun's dormmate and currently a culinary student in a university. Him and Woohyun know each other a lot as they were already friends since high school. He would go to HyunStar Ent. which is just about a five-minute walk from his dorm to give some people samples of his dishes and food masterpieces after the talent company has been recently opened.

 Jang Dongwoo - 22 y.o. - Included in Myungsoo's group of friends, and he works as a host in radio shows and live event shows. He's outgoing in a great way and has a collection of dinosaur stuff toys (about 50), and he almost won't lose stuff to talk about. He really loves to have fun and then do funny stuff with his friends, and he has a lot of knowledge too.                                                                        

  Hirai Momo - 20 y.o. - Dancer/Choreographer in HyunStar Ent., and also joined the same dance club with Hoya back then, so they know each other a lot. Might develop a crush on someone there... She is also quite cheerful.

  Jung Eunji - 20 y.o. - Woohyun's best female friend, and is in the works of being a K-Pop idol also under HyunStar Ent. 

   Lee Jung Hwan (Sandeul) - 22 y.o. - One of the head mentors along with Sunggyu, another young "representative parent" in HyunStar Ent.
