⟪ PERSONALITY ⟫
Traits : 
→ Positive : Hardworking, mature, polite, responsible, honest, caring
→ Negative : Cold, boring, bossy, strict, picky

 + Nari, ever since she was little, was always a hardworking and focused girl. She loved to study as she found it fun, and she would always aim for the best so she'd always focus hard on everything (this includes the future and where she works now in the present time). When she was in school she kind of had OCD and people would question her because they thought it was weird. Nari is strict and caring by nature, it may be contradicting but hear me out. As for being strict, Nari had learned to be independent to take care of her parents, thus resulting her in becoming mature for her age, she was strict on things like rules and thought that rules were the way of life and we always had to oblige to it. This also made her bossy as she would tell people to follow the rules and will always order them around. This could also make her a bit picky. In all honesty, Nari doesn't get pissed off as easily, she is very patient and can handle a troublemaker without having to blow and start raging everywhere.

 + As for being cold, Nari is unintentionally cold, she has no idea why she's cold but it might be an effect of her sister's death (more explained in the background). However as for being the mature girl she is, she's very polite especially to her customers, Nari works at Seoul Cafe - a job her long time friend offered her. She's kind as she got such trait from her mother - genetics mate. She's honestly kind and caring to her customers and they've dubbed her that Ice Angel because she's kind without a smile. So you could say her politeness is her kindness. Nari is also honest, she doesn't like to tell a lie, her mother had always taught her to be honest and to never tell lies, and she listened. So Nari, being the mature girl that she is, is actually very responsible, she doesn't make any excuses as she thinks they're useless, she won't fight or argue with anyone as she also thinks its a waste of time and she will always take responsibility as she thinks it's childish if she doesn't.

⟪ BACKGROUND ⟫

 + Nari was born and raised in Paris, France. Her family weren't very rich back then and only relied on the people around them to help them out with finance, what they didn't know was that it was going to bite them in the . When Nari was in middle school her parents were soon chased by loan sharks and were told if they didn't leave the country they'd have to pay full in one weeks time. That's how they moved back to Korea - Nari was about 13. However they still had to pay the loan sharks but it didn't matter how long it took, they just needed to pay them back. Nari's parents aren't the smartest and the only reason they lived in Paris was because they had family there but passed away when she was born, now that they're in Korea it was easier to get a job however hard at the same time and Nari's mother was the only one who could afford to get a job as well as her older sister, Nakyung. Because of this, Nari had to mature quite quickly as she wanted to help her family survive. By the end of middle school she was already secretly taking up jobs to help pay for the rent and the loan sharks.

 + Nari was always a hardworking girl since the moment she stepped into elementary school, she seemed emotionless and scary at first so she hid her eyes behind glasses so the kids won't stay away from her. However she had a kind heart and was caring by nature. She was always on top of the class however there were times when she would be in 5th place. She was smart and intelligent and spend most of her time studying however she never missed a time to have fun. Nari had a older sister by 5 years and her same was Nakyung, as stated before. She looked up to her sister a lot as they were both really close and she was the prime reason that she ever smiled. Nakyung was outgoing and social and she would always have above standard grades at the same time and Nari envied that because she could never keep a soical life since it wasn't her. Nakyung, along with her best friend Lee Soojin, would spend a lot of time with Nari and would always keep her up to date with everything since they both knew that she couldn't keep a social life. Back then Nari was always cheerful and she smiled a lot, she was able to still have fun and keep working hard at school. However when Nari was in high school and Nakyung was 21, she (as in Nakyung) had died in a car crash to work, this effected Nari for the worse. This is how she became so cold and distant. Nari was emotionless for a year (or a month, week), she couldn't find a reason to smile nor go to school, all she did was work, work, work and work. However Soojin was there to comfort her and to help her get back onto her feet again. Now Nari takes a lot of things seriously, she always did take things seriously especially because of the fact her family is poor, however because of this her maturity level had risen and her independence grew. Her independence didn't only come from her sister, it also came from her parents, she knew she had to become independent for them. She values her family more than anything.

*Note: Nari's parents moved to Paris before or when Nakyung was born. Nari is very close to her family, even though it mentions her sister a lot, she feels more special and close towards her mother. Feel free to change or tweak anything if Nari is chosen, because I know that her background might be confusing since I am known for making confusing background, keke sorry it's just that when my juices get flowing my writing just splatters everywhere. If confused: Nari became mature to look after her family and because she didn't take Nayoung's death in too well, thus she became more strict.

*Omg! I hope her background story doesn't sound too sad ><

⟪ PLOTLINE ⟫ Complete Opposites
⟪ BACKUP PLOTLINE ⟫ Did You Remeber?

⟪ HER REACTION TO THE PROPOSAL ⟫

 + Twitch. Why in the world is this idiot asking me to be his wife?! Every single day he comes into the cafe and cause a ruckus, then he starts to walk behind the counter and plays 'pretend' cashier and then he starts to eat all of the food without paying! And worst of all, he always gets away with it. What is he? A baby? And now he's asking me to be his wife?! Twitch. The screaming of the girls behind him made me even more annoyed. My eye couldn't stop twitching, it was a new record. Twitch, twitch, twitch. I AM NOT BEING THE WIFE OF A CHILDISH MAN WHO IS MEANT TO BE OLDER THAN ME! Right after I came back to my senses I stomped on his foot and slapped him, that's what he get's for asking a girl he knows little of to marry him. Goodness. 

 + Nari's parents reaction when she told them: They were happy for her and were glad that she found someone she 'loves'. Okay in all honesty this is the first time that Nari had ever lied to her parent, she knew that they wanted the best for her, especially if it involved a rich family and Sandeul's is one. Nari told her family that she was going to get married to someone she loves, which was a lie and she felt incredibly awful about it that she even though of telling the truth to everyone, literally everyone. Her parents were overly exited about her getting married and were over reacting and as for Nari, she left as if her life was over. 

⟪ THE REASON ⟫

 + Sandeul is pretty well known thanks to his family being pretty wealthy but not too rich. He does have some fan girls but he never really cared about it since he would always get food from them and he loves food. Okay, on to the reason. His family was sick of Sandeul always being so childish about everything and want him to grow up since he's already like 25 years old, a grown man. So they thought that a wife would be a perfect fit for him, seeing how a woman can change a man and they were hoping that if he got a wife it would change him for the better, and make him more mature. If he refused his family would like disown him, not really, just stop spoiling him and making him work for his won money. His family thought of a system, they would pick out 5 girls for him to choose to be his wife in a one month time span and after he picks one of the girls he would be married to one of them for 3-6 months (you can choose) to prove his maturity and then after that, he gets to choose whether or not he wants to stay married to her. However those 5 girls were super ultra obsessed with him. So he did what every man with a stalker would do - run away. So he ran and ran and ran until he stopped at the Seoul Cafe, there he saw Nari and immediately told the girls that she was his fiance. Then blah, blah, blah, Sandeul found her the next day and asked her to be his fake wife until the system is over. He didn't just choose her randomly, he knew that she was a mature girl and thought that his parents would be happy if she was around, also Soojin knew that Sandeul didn't like the girls his parents choose so she recommended Nari even though knew she what her answer would be. 

⟪ PERSONALITY ⟫

 + Sandeul is a kid in a man's body. He lived in a wealthy family but not too rich and would always get spoiled by his parents so in reality he never really learned to grow up and mature. Sandeul is a childish man who is always seen randomly jumping around and smiling whenever he gets the chance, it's rare to see him sad. He's always cheerful and bubbly and will always liven yup the mood when it gets serious, he's always optimistic about everything and will look on the bright side plus he is always energetic and can't find the time to sit down and have a talk. He can seem like an idiot because of his lack of common knowledge and is always making trouble whenever he can may it be on purpose or by accident. Sandeul is actually a carefree man as well, he has no worries in the world and that also makes him a trouble maker and cheeky. With his trouble making attitude, Sandeul likes to play pranks in his spare time or just whenever he feels like it, he'd always play pranks on the guys and the customers in Seoul Cafe. This resulted in him getting kicked out multiple times and even getting banned from the cafe for a month.

 + Sandeul, overall, is a baby. He uses aegyo like 24/7 for everything and this is how he is able to get out of sticky situations. He has a baby face and would always use it for getting what he wants which would always work on his parents. In all honesty he's also a bit of a scardy cat, only with things such as ghost, lighting, thunder and the dark but he can handle a scary movie. However despite some of his bad traits and his overall baby-ish attitude, there can be times when Sandeul can be mature and warmhearted. He can't stand to see a girl cry and would normally have a very civil conversation if someone is having a rough time and he feels like he needs to get involved somehow. He has shown his caring side to his younger sister, Lee Jungmi, this is not that common though but he does sometimes look like an older brother to her however sometimes it's like he's the younger brother.

⟪ INTERACTIONS ⟫

 + Nari hates Sandeul. Sandeul dislikes Nari with a passion. Sandeul would try his best to be nice to her but she was always uptight and boring which he hated. Nari was on the same boat however she hated Sandeul because he was too childish for his own good, and she didn't like how he was older than her yet he seemed 10 years younger. Nari works at the Seoul Cafe and Sandeul goes there as a regular customer, he would normally cause a ruckus and Soojin wouldn't be so hard on him for it. Nari hates this and tries hard to not yell at him since he's a customer, but it doesn't work and she normally kicks him out even though she's just an employee. He's is basically the only person who can make her so angry that she would yell and sometimes have a rage fit...like a very, tiny rage fit, like really small. 

 + When she became his wife (it took a long time to convince her, then he mentioned money and she was in) she thought that living with him wasn't going to be a big deal but she gets even more annoyed then before seeing how he was the one starting stupid and childish fights that she doesn't want to get involved in. He would complain on the littlest things like a baby and whine a lot when she doesn't get him what he wants. Nari acts like the mother of the fake relationship, it's weird but she's so strict and stern about everything in the house which annoys Sandeul as he hates people ordering him around. She has set up rules around the house especially with the one sleeping in the same bed - Sunday to Wednesday she sleeps on the bed while on the rest of the days he sleeps on the bed, plus everything has to be labeled around the house. Once you step into their house you immediately hear yelling and Nari isn't the type to yell at all, she would normally take things seriously and maturely in and orderly matter but Sandeul is too hard to control so she yells at him like a mature adult - or like a mother to it's naughty child.

 + She was amazed at how rich his family was and that she didn't believe a childish man would live in such house, she was just staring at awe while Sandeul talked to his family. Sandeul's parents are in love with Nari, like seriously, they like her personality and they've bet their whole money that she'll be able to change Sandeul, however they don't like the fact that she isn't one of the girls they choose for him.

 + After some time (this is basically their whole story), Sandeul got sick of Nari's personality, he really didn't like the bossy pants that is Im Nari so he decided that he'd change her. He would tell her to loosen up and to smile and have some fun once in a while. He tries to get her outside and to stop working for once. He would try to make her fun and do fun things with her like trying to plan vacations or like little trips however they would never work out. But he'd try to do things that she likes to do and would try to make her smile. So basically you can say that Sandeul is like a teacher to Nari, he teaches her the values of life and to live it to the best and to live it like it's your last day on earth.

⟪ THE MEETING ⟫

Sandeul and Nari already knew each other before the story had started. About a year ago (or whenever you want) Soojin offered Nari a job at Seoul Cafe, and she gladly accept. Sandeul has known Soojin for a long time since he has become a regular customer ever since the cafe has first opened. The moment Nari had met Sandeul was the worst moment in her whole entire life.  It was her first week at the job and she was already getting use to the regular customers, however Sandeul wasn't there because he had to go on a trip with his parents, when he arrived Soojin introduced them to each other as Sandeul was a regular customer. At first Nari thought that he was just a cheeky guy and didn't really care about him since she could hold her patients. However after time went on and she realized this guy was a year older, she got sick of his carefree and careless attitude that 24/7 she'd kick him out of the shop for causing a ruckus. 

He would always annoy her and it was the first time in history anyone could do that, literally and even Soojin was surprised at how annoyed Nari got. Since she was always such a mature girl and would always handel things responsibly, no body ever thought she's get so irritated at one boy, but it was possible. He'd always be a trouble maker, always playing pretend cashier and pretend waiter - it annoyed her that he wasn't take things seriously and the worse things he does is go to the back and make a mess in the kitchen while eating all of the food without paying.

A moment between Soojin and Sandeul about Nari that you could possibly maybe add if Nari's chosen:

"Why is she always so cold?" Sandeul sighed as he asked Soojin.

"Since she was born she was always cold, if you'd met her before you wouldn't even think that she was that age, her maturity level is higher than expected but she would always find time to have fun and smile. However everything went downhill when her sister died."

"She had a sister?!" he looked up at her in shock.

"Yeah... but she passed away in a car crash."

"I... I didn't know," he whispered with a guilty look. 

⟪ THE ENDING⟫

6 months (or 3 months or whenever you want the system to end) has already passed and the system was going to be over and done with on the next day. Nari and Sandeul spend their last moments as a 'married couple' but it wasn't like they weren't ever going to see each other because of work. However instead of Sandeul proposing this time, it was Nari. She thought about the things that he has done for her these past few months and the fact that she has grown a liking to him plus she thinks she'd falling for him, he was there to cheery her up in the bad times and there to support her through the rough times. She didn't want those memories to just be a memory, she wants them to last forever so what she did was plan a surprise at the Seoul Cafe that involved everyone (maybe like that other chosen apps and their love interest?). She had everything organised so neatly, the chairs and tables were no where to be seen and had roses everywhere, something a guy would do in this situation. When he walked in everyone hid behind the counter and Nari stood there in place with a ton of rose petals surrounding her. This is how everything else went:

"Nari?" Sandeul questioned.

"I apologise for being so rude to you through these past few weeks! I was cold and distant and I was really strict on you because you always acted so childish, and in all honesty you made it on the top of my list for the person who could actually annoy me. I know that I was bossy and was more like a mother than a wife but I promise you it won't happen again!" she blurted with a hint of nervousness in her voice and face a flustered.

"Wait... does that mean..."

"Please marry me!" she yelled with her face facing to the ground as she tried to hide her scarlet coloured cheecks. 

"You must be stupid..." he trailed off.

She looked up at him as she had already been rejected. 

"If you think I'd say no," he smiled wider than he ever did before.

He ran up to her and hugged her and she kissed him on the forehead. Sandeul laughed and thought that she was still acting like a mother so he kissed her on the lips... and you know what happens next~ ^^
