♚personality — This bloodtype O girl has a very independent nature, plus her very energetic character which spreads out her positive vibes around. She had always been admired for her kindness and helpful nature. Yoon Jae is also quite optimistic and very ambitious, especially when it comes to her interests, such as basketball and music. And she takes opportunities as a challenge for her. If she fails, she would always try to work her way up again to succeed. Like her favourite quote from her idol, Michael Jordan, 'I've failed over, and over, and over, in my life, and that is why I succeed.' Moreover, this girl is full of youthful enthusiasm and overflowing confidence in herself which makes her hugely popular among people. With a fine combination of humour, wit, and strength, plus a dash of feminine charm, she doesn't really have to work hard to attract people. Being a party girl, (she loves to go parties...), she loves being the centre of attention. As a friend, she would always stand by them through thick and thin, till the very end. That is to say, till they had solved their problems her friends may be facing. She doesn't want to be too involved in their problems, but she would certainly give them all the care and help they needed. Yoon Jae can sometimes become impatient as she likes to deal with her work quickly. She also can be quite possesive and tend to become jealous easily, for example, she doesn't like to share her friends with other people. She was often described as shallow and lazy. Well, the lazy part is true, as she hates to do work or anything if she was not asked, especially studying. But who would know that this party girl could top the scores in her school? She can be shallow at times as she always see people by the looks first, then the personality, like a person judging a book by its cover. She hates being shallow, as she almost losing her friends because of this trait. Patience is not her strong suit, and it takes a lot of convincing to make her change her decision. Ironically, she can be arrogant at hurt other people's feelings as she is very straightforward (She can't control ). If she was rubbed in the wrong way, she can be hot-tempered and quite dramatic, so apologizing her won't be a good use as she prefers to be calmed down by herself. You won't see smiles on her right away, in fact, she might distant away from her friends. This is somehow a weakness from Yoon Jae, she could be a good friend to anyone, always helping them out, but a good friend to her is quite hard to find, as it's hard to find someone who tolerates with her hard-headed character.

♚background — She existed in this world on May 10 1995 in Daegu. Only she wasn't alone in her family. She still lives in Daegu, South Korea with her mom, dad, and her two noisy oppas, making her the youngest in the family. Her mom owns a famous restaurant in Daegu, while her dad 'owns' a basketball team, the Daegu Orions. Yoon Jae is close to both of her oppas, and yeah, both of them kinda spoil her, showering her with love. (The protective oppas, even more protective than her parents) And both of them showed her music, which became part of their lives They taught her on how to make some mix tapes, tracks, and covers. They sometimes ask her to sing for them. Sometimes, her brothers teach Yoon Jae on how to play basketball. (Her dad's a coach, so...) When she was 15, both of her brothers left their nest, trying to pursue their dreams, but she still managed to get in contact with them. and was going to pursue her dreams as a music composer, as she wanted to be like her brothers, although one became an idol, but still, they managed to change the world of music. So she started making her covers, and post it on soundcloud and Youtube (under the username, MissJayMin) to help her improve her skills in singing, and sometimes dancing (a trait she inherited from her dad -wondering why her brothers didn't have it-),  which the channel became famous, although no one knows who she really is (except her brothers.) After being requested by a random follower to audition at BigHit Ent, so she tried and was finally accepted, when she was 17 and two years after, she transfered to NH Media. She continued her studies in Seoul Institute of Arts, majoring in music composition.
