When a new company, D2 Entertainment, created a whole new system to debut a new group, they’ve brought many rising idols to mentor these many trainees. From groups like VIXX to rookies like GOT7, D2E gathered them into one place to train these trainees for success while competing in a tournament versing other trainee groups. How will these members act with each other and moreover live altogether?!

Seo Chi Hae and Cha Eun Jae have known each other since elementary school. Being the best friends they are, they share the same dream of becoming rising stars in Korea. For four years they have continued as trainees at D2E and met new people along the way like Boram and Mei Yun. Through the competition they have met new friends like Soo Hyun and Ji Young. These 6 girls are in a trainee group named “A-Game”.

Seo Chi Hae: (21 yrs. old) Hard-working girl who trained in D2 Entertainment for 4 years. Leader and main vocal of the created group from the new training program/competition. She is an all-round performer in singing and dancing and is one of the longest trainers in the group. She works for her dream so much that sometimes she overworks herself. She respects all the idols and would rather call them “sunbaenim” than “oppa.” However, she is hesitant to express her feelings towards her mentor Leo, knowing too well about the consequences of dating an idol.

Cha Eun Jae: (20 yrs. old) A bubbly personality who is Chi Hae’s best friend ever since elementary school. Sharing the same dream, she also has been trained for 4 years. She is the other main vocal and visual for the group. She can also be very straight forward towards others and protective of her close friend, but also has hard times handling her feelings. Eun Jae likes to form close bonds with the people she meets, so she calls most of the idols “oppa”. She has a huge crush on Ken and isn’t afraid to show it.

Leo: (23 yrs. old) Better known as Jung Taekwoon, this main vocal in VIXX is paired up with Chi Hae. Although he seems distant from everyone else other than s, he seems unusually close to Chi Hae. With uncertainty of his feelings, he gradually gets closer to Chi Hae.

Ken: (22 yrs. old) Also known as Lee Jaehwan, Ken is the other main vocal in VIXX and is Eun Jae’s mentor. Both him and Eun Jae share a similar bubbly personality and love to make gags and laughs for the group. Despite his cheerful exterior, Ken holds a secret painful past that only s know of.
