Seo Joo Hyun (Seohyun) : Seohyun is a polite diligent girl who goes to Seoul University. Even though she is in SNSD, she never brags nor act arrogant, not even once. She considers herself as a normal student who has beautiful unnies. Seohyun never was interest in dating boys or just like...thought about them in that way. She never had an eye on a boy, not even the school kingkas. She never even thought about dating someone. Seohyun just wanted to graduate college and major in Literature, then maybe she might think about having a boyfriend. But not now. This is one of the most important moments in her life! If she doesn’t try hard, then she won’t get a good job! …..So no boyfriend until then. That’s what she thought before but now she is engaged the son of her parent’s friend. And those type of guys are the one that Seohyun doesn’t like. And why does it have to be the school kinga? That guy makes Seohyun lose her patience too. And now one of her unnie, Jessica is bothering her more often now. She has a feeling Jessica Unnie will do something.

Kim Jong In (Kai): Kai is one of the school kingkas in his university. How couldn’t he be? His looks are flawless and his academics are perfect too! (even though he doesn’t try). He is like a natural perfectionist! Girls fall for his badass cocky attitude and his handsome face. But he doesn’t have a single interest on girls. Just none of them catch his eyes.He and his hyungs are known as EXO in his university. Kai also has a normal life with his hyungs until his parents announce that he is engaged to a girl. WTF??? She isn’t from a rich family like him or she is extremely beautiful. Just an average girl who goes to the same university has him. Just because she is in SNSD doesn’t mean Kai likes her. What’s so special about her? Oh wait... One thing. She doesn’t even show a slightest interest in him. Not only him but other exo guys. Shouldn’t she be at least like giggling or chilling around with EXO if she is in SNSD? Does she really not have an interest in Kai or EXO at all?

Jung Jessica: Jessica is one of the oldest girls in SNSD. She is also very known around the school. Her beautiful face, her angelic singing voice and her blonde hair makes her seem like she is from heaven. Such a wonderful girl.... That’s what you would think but her personality can be a bit y sometimes. Jessica needs to be in the front when SNSD is walking down the hallway. She needs to be the fashionista in her group. She needs to be richest, she needs to be- You get my point. Jessica has a habit of doing anything to get what she wants. She gets along with everyone except Seohyun. Why? Because... they are so different. As the member of SNSD, she should be going to parties and dates but what does she do instead? Read. Study. Write. Listen to music. And guys fall for her innocence??  That’s what she calls acting. Does she even realize that how lucky she is to in SNSD? And now, the guy that Jessica likes is engaged to Seohyun?

Luhan: Another kinga of this school, known for his cuteness. His shy smile make girls’ heart skip a beat. Even though he is a third year, people mistaken him as a first or second year due to his young looking face. It seems like he likes everyone. Even though he turns the fan girls down, he still thanks everyone of them. Luhan seems like he has no interest of dating girls. But in his mind, there has been one girl that he had his eye on for a while now. Seohyun. Her innocence and the fact that she doesn’t really care about money, fame, and fashion is so... unique. Isn’t she a member of SNSD? Shouldn’t she be acting like her unnies? Does she even have interest in EXO at all? Does he only keep on an eye because of only that reason or something else? Her politeness and humbleness makes her stand out more. But now, the girl that doesn’t even glance at EXO in the hallway is now engaged to one of the EXO members? In addition, Kai? The guy who doesn’t give a about anything? So does that mean he have no chance with her?

Kim Taeyeon: The leader of SNSD also like the mom of SNSD. Taeyeon gets along with everyone and she is liked by everyone in SNSD even Jessica. Why? Her bright obedient kind personality is impossible to dislike. Taeyeon especially cares about Seohyun, not only because she is the maknae but it’s just that.... She is different. Whenever Taeyeon invites her to a party or a club, she refuses to go. Why? Every girl in planet would like to go to a party with expensive clothes and have fun with EXO. Does she really not have an interest in those twelve good looking guy? Taeyeon is dating Baekhyun now and they are a happy couple. She asks her boyfriend sometimes how she can make Seohyun be comfortable with EXO. But now, that Seohyun who never even talks about guys is engaged to Kai, one of the EXO members who is also the heartthrob of this school?

Do Kyungsoo (D.O): Even though Kyungsoo isn’t the leader of EXO, he acts like one. More like motherly(?) caring. He cooks for his group and he just cannot stand untidiness like Seohyun. Everything. Needs. To. Be. Organized. Even though he is a year older than Kai, the quiet but coldhearted Kai tells Kyungsoo his problem. It seems like Kai is really comfortable with Kyungsoo and Kyungsoo is also comfortable with Kai. He sometimes know about Kai and what he wants more than Kai himself. Kai and Kyungsoo are the only members in EXO that doesn’t have an interest with parties and girls. But Kyungsoo doesn’t have a cold hearted cocky attitude like Kai. He is like the girl version of Seohyun only a bit more sociable. Kyungsoo doesn’t really judge or wonder about Seohyun that much. But he does notice that she is quite unique. She is better than those nosy fan girls out there. Will Seohyun change his dongsaeng?

Im Yoona: Yoona is the second youngest in SNSD but one of the prettiest. Like Jessica, she is known for her cute aegyo and smile. Her popularity is similar with Jessica but she doesn’t try to compete with anyone. She doesn’t have to be the best like Jessica. Yoona is closest with Seohyun and Yuri. Seohyun tells her problems to Taeyeon and her. Yoona cares a lot about Seohyun. She treats Seohyun like a sister. But their personalities are different though. She is really outgoing and at least goes to a party every week. She makes new friends every week and

goes to club with them. But Yoona thinks that it’s Seohyun’s choice whether she goes to parties or not. And that’s why they get along. Taeyeon and Yoona talks about Seohyun and they try to help her a lot when Seohyun is having hard times. She seems to have an interest in              .

Byun Baekhyun: One of the most outgoing guys in EXO along with Chanyeol, his best friend. Baekhyun is bright, cheerful, sociable and he also can be . Even though he is a third year, he can be a bit childish. He use to be very flirty until he met his current girlfriend... Taeyeon. He truly cares about Taeyeon and shows lots of affection to her. He gets jealous easily about Taeyeon. Baekhyun gets along with everyone in EXO even Kai who doesn't really socialize. Kai doesn't seem to mind about his bright personality. Of course, he is loved by all the SNSD members except Seohyun. But most of the times, he doesn't realize that she is there anyway so it doesn't really matter. He started to notice more of her when he started to date Taeyeon who looked around for Seohyun every hour at least. It pretty surprises him when he hears that Seohyun that girl is engaged to Kai.What a surprise!

Hwang Tiffany: She is a third year like most of the SNSD including Jessica and Taeyeon. Tiffany is outgoing like Jessica and Yoona, well like the rest of SNSD except Seohyun of course. She is very famous for her pretty eye smile. One of those smile make her fanboys go wild. Her favorite place to go is the beach or night parties by the pool. She loves to drink at parties so she can become a bit drunk. Tiffany is closest with Jessica. She also can get annoyed by Seohyun's role model attitude but she doesn't show it. Like Jessica, Tiffany thinks that Seohyun should go to parties with the group and not act all innocent. How could it be not acting? Not having an interest in EXO no a boy doesn't make sense in this age. Doesn't she want to hang around with the school kingkas? Also Tiffany has a clear feelings for Luhan but why does it seem like he has an eye on someone else?

Wu Kris: Even though he looks cold but he is very sociable and can talk to anyone. Even though he is a third year, he is naive and innocent. Because of his sociable personality, he makes lots of friends at parties and clubs. But his closest friend is Tao. The only people that he can't easily talk to are Seohyun and Jessica. Seohyun, well first of all he doesn't see her a lot because she doesn't attend lots of parties. But Jessica is a whole different reason. Whenever he looks at Jessica, his heartbeat skips a beat. It feels like she is the magnet that is pulling him over to her. He just doesn't have the guts to talk to her. Weird huh? The outgoing personality can't work on the woman he has feelings for. When he hears that quiet Seohyun who doesn't stand out is engaged to Kai, he is a bit surprised. He is a bit curious about her but what's more curious is why Jessica's attitude changed when she heard the news.

Kwon Yuri: Yuri is also a third year who is known as the "black pearl". Her skin is a bit tan (no racism) and she looks the most beautiful when she is swimming so that's why she is called like that. And she is known for having the nicest body in SNSD. She likes attending pool parties with other members but she dislikes going to bars because she is weak on alcohol. So she prefers drinking wine than other drinks. She currently is closest with Yoona and Hyoyeon. Because of Yoona, she started to care way more for Seohyun than before. She sometimes stay with Seohyun at home when other girls are leaving to a bar because she is afraid she might get drunk again.  

Chanyeol, Suho, and Sehun:

Chanyeol, the second year shows lots of affections towards SNSD. He flirts a lot with his fan girls and his habit is to wink at girls whenever they are passing by. Like Baekhyun, he gets along with everyone in EXO and SNSD except for Seohyun. He rarely sees her outside school and he sometimes wonder about that. But it doesn't bother him at all. If he can't flirt with her, then that is fine with him. There are other girls in this world, right? But that girl is engaged to one of our maknae, Kai? Wow, that's a surprise.

    Suho in the other hand is very polite, considerate and exemplar. He has the most similar personality with Seohyun. He and Luhan were the people Seohyun talked to when all the EXO and SNSD members meet. Suho and Seohyun's conversations are mostly about books and schools. He probably was the closest member with Seohyun in EXO. But Suho never expected to get marry this early. And to Kai? The guy who didn't have interest in girls? What happened?

      Sehun is the youngest in EXO along with Kai. (His birthday is faster than Sehun's) He is shy at first and doesn't talk that much but once people get to know him, he is very lively! When EXO and SNSD first met, he was one of the quietest but now, he and Chanyeol are the first ones run to SNSD when they spot them.

Kim Hyoyeon, Choi Sooyoung, and Lee Soonkyu (Sunny): Except Sooyoung who is in second year with Yoona, Hyoyeon and Sunny are in their third year.

Hyoyeon is a party animal in SNSD. She just loves going out to parties and clubs. Especially at night times. When there are some good musics, baam! She turns into a dancing queen. She is the best dancer in SNSD. She is very outgoing and cheery. Hyoyeon tries to teach Seohyun some dance moves to get some boys' attention, she politely refuses it. That kind of girl who never had a boyfriend is engaged to Kai?

Sooyoung is the tallest out of SNSD. She is also very skinny but she eats the most. She makes fun of those short members like Hyoyeon,Sunny, and Taeyeon. Sooyoung slyly takes some of members food often. She eats so much especially when she goes out but she doesn't gain an ounce. She is easy to talk to and she smiles a lot. Sooyoung is close with Hyoyeon and Sunny right now.

Sunny is one of the oldest but shortest in SNSD. But she is known for cuteness around the school She has the most aegyo in the group. She can be sensitive about her height and often is mistaken as a first or second year. She is very flirty with boys especially to boys who are younger than her.

Tao, Xiumin, Chen, and Lay:

Tao is a second year who seems expressionless but he is the most sensitive member in EXO. He can get very emotional and let's it all out in parties so sometimes he can go wild but that is why girls fall for him. Tao gets along well with Kris.

Xiumin is one of the oldest in EXO. Like Kyungsoo, he is very organized and neat. He also is a very hard worker. Xiumin unlike Tao, he is very self controlled in parties and clubs even though he can drink a lot.

Chen: A second year who is known for his gentleness impression. He is a bit quiet and mostly laughs softly. He can be a bit awkward at parties and clubs because how quiet he is. Chen cares a lot about every single members equally.

Lay is a third year who is very easy going and forgetful. He is also the funniest in EXO. He loves going to parties. He is always very lay-backed and has no worries. He loves being with girls especially at school ( but he doesn’t remember any of their names).
