Cheonsa has such a vibrant, energetic, outgoing, spirited personality that she practically glows. Her witty remarks and go with the flow attitude make her variety gold. She's also pretty determined and passionate - causing her to do what she wants to do. She's also a warm and compassionate person who tries to help anyone she can. She also stands for what she believes in and cannot stand injustice. Cheonsa's also creative - she thinks outside of the box. She's very adventurous and likes trying new things. She's also very loyal to those who've earned her loyalty. She's also pretty quirky - in fact, she actually preparing for an apocalypse.

She's not all sunshine and rainbows though. She's very sensitive and emotional; this girl is the definition of a bleeding heart - she gets hurt easily, though she tries to make it not obvious; she also doesn't like it when other people get hurt and doesn't want to hurt anyone. She's also conscientious and insecure - even when she's on a variety show, she thinks of what the repercussions of her actions and words might be (though, she once again tries not to show it to not upset the fans). She doesn't like to make things obvious and bottles up things that bothers her, mainly because of her utterly misguided thoughts that it would just be a burdern to people. Cheonsa is also absent-minded - as passionate as she is, she has the tendency to daydream and forget about stuff. She can also be shy sometimes before her variety self kicks in.

Cheonsa was born as a healthy baby girl on May 18, 1993. Five months later, her parents were killed in a car crash and she was put on adoption, as both of her parents were orphaned, only children. A Luxembourger couple, Emil and Anais Roux, visited Seoul and fell in love with the baby they saw in the orphanage. Due to complication from their third son's brith, Anais couldn't get pregnant anymore but had always wanted a girl. Her husband, had the same dream as his wife, and so, they adopted Cheonsa and renamed her "Angela Roux". Their sons, Damien (11), Marco (8) and Simon (4) didn't mind that much, though there was a bit of hostility coming from Simon at first, since he thought that Angela would take over his place in his parents' hearts.

Growing up as the daughter and youngest child of Emil Roux, the CEO of Roux Industries, and Anais Roux, a famous fashion designer, made her a very lucky girl compared to other people. She grew up wanting for nothing and had everything she could've ever wanted or needed. She was practically a fairy tale princess come to life. Thankfully, Emil and Anais were level headed, modest people, so their children didn't end up becoming entitled, spoiled, whiny brats.

Angela's childhood was spent on school, her family, her friends and the lessons she wanted (which included dance, voice, acting, modelling, piano, horseback riding, fencing, archery, painting, cooking, baking, ice skating and gymnastics; some were prioritized more - like voice, acting, modelling, piano - while others were just hobbies so she only took lessons every now and then - like fencing, painting, horseback riding). Her parents could tell their daughter was a performer at heart and encouraged her to do whatever she wanted. She never got the best grades in school, but she wasn't the worst either.

After graduating high school, Cheonsa made a decision to go to university in South Korea. Despite living in Luxembourg, she still tried to maintain her Korean roots - which is why she's a big hallyu fan. Her family was reluctant because they wouldn't be there but her determination eventually made them agree. She got into Korean National University of the Arts to study vocal music. One day, while shopping, she was approached by an SM scout. He told her that she would make a great model or actress and gave her a card. Cheonsa was disappointed they saw her as just a beautiful face and a good body. Yeah, she does love modelling and acting, but she had always dreamed of being a singer. She decided to audition to be a singer and was accepted. One thing though, Cheonsa didn't tell her family that she would be auditioning (okay, maybe it was a bit of a rebellion, but she wanted to do what she wanted without being afraid). Man, were they (though more her parents) angry. They didn't want her to be an idol or singer because their lives were hard - there would be haters, they lack privacy, sasaengs, basically, it was just too dangerous. Sure, her parents encouraged her performing arts lessons but they didn't think she would actually be a singer. Her brothers were more understanding though. Cheonsa put her foot down and told them that this was her dream. It took a week of constant arguments before her parents relented.

And so, Cheonsa's life as a trainee started. It was hard and exhausting. There were the trainees who tried to bring you down so that they could climb up. The lessons which tried her patience and determination. The teachers who were unrelenting and strict. However, she managed to pull through and was chosen for Neon Butterfly.

Seunghyun is known for his cool, mysterious image. He's also known to be a firece performer and a charismatic and great actor. His strong features and deep baritone voice makes him look serious and intimidating. He's also known for being fashionable and a lover of art and wine.

Despite all of that, he is a sweetheart who is caring, gentle and kind. He's also a kid at heart so he can be pretty childish and playful. He loves toys and crazy hats. He's also a modest and sensitive person. Seunghyun is also very hardworking and passionate. He's also a funny guy despite his serious look. He can be insecure at times and he's afraid of showing too much of himself to people. He can also be awkward, clumsy and shy at times. Also, he can be extremely stubborn and speaks his mind. Oh, he can be erted too (understandable, since he's a man). Basically, he looks like a tough, manly man, but he's actually a manly, teddy bear.

FIRST MEETING: The first time they met, it was during Big Bang's fansign event. Cheonsa was young and looked different due to lack of idol styling and obviously, Seunghyun doesn't remember her now.

BECOMING FRIENDS: The next time they met, it was backstage during Inkigayo. Big Bang had just performed and the accidentally bumped into each other. They both apolgized and went their separate ways. But then, they kept bumping into each other - even outside of music shows and broadcasts. In the end, they ended up becoming friends and exchanging numbers.

AS FRIENDS: They end up becoming great friends, which is hard since the guys in Big Bang don't do friendships outside of each other much. They like to joke around and buy each other presents. Since they're idols (and Seunhyun is a pretty recognizable star), they just kakaotalk when they're not on a music show or broadcast with each other. Seunghyun even introduces her to Big Bang, who accept her like a sister.

DEVELOPING RELATIONSHIP: The way they developed feelings for each other isn't sudden. It just grew slowly, taking its time. They were oblivious to it at first and everyone around them thought they either had feelings for each other or that they're already (secretly) dating. They only realized while hanging out with each other and think, "Man, it was so obvious, why didn't I realize?" Seunghyun isn't the type for relationships, so he's pretty serious of his feelings when he asks her out.

AS LOVERS: Seunghyun is the manly and sweet lover. He's really considerate and caring towards Cheonsa. He doesn't mind her talking to other guys as he knows she's his and that she's a loyal girl. He also likes buying gifts spontaneously. Other than though, he would be the weird boyfriend, cheesy, silly boyfriend that would make Cheonsa laugh a lot. He's also a bit of a (but hey, practically everyone is). Cheonsa is a sweet and considerate lover who likes to send encouraging and "how are you?" messages to her boyfriend. She likes doing small, but meaningful things with him and appreciates everything he does and everything they go through together. They love each other - flaws and all. They aren't the skinship type of couple when in public but you can definitely tell they love each other. In private, they like cuddling and talking with each other a lot - it makes their relationship stronger. When they argue, they would go to another place to cool off. Once they've cleared their heads, they would apologize and make a compromise.

END GAME: They end up a strong couple. And they get engaged and married yesss
