personality: 

"do not disturb me, i'm so gonna score aces." - constance is a very hardworking and talented girl. always burning the midnight oil and sneak into the library so as to be able to gain 'extra knowledge'. to her, putting effort and taking the initiative to learn new things is considered a hobby and also a privilege. if you happen to defeat her in certain tests, mark my words; constance will be in the library and will get very little sleep. she was in ravenclaw, she's supposed to be a smart girl and no one was going to change that fact. besides being an obssessed hardworking nerd, constance is also very alert. she can definitely spot if there is something unwanted in the room. however, she's not as brave as she would depict herself to be. rather, she's a scaredy-cat dressed in a wolf form to pretend that she's strong and that she's brave. i mean what do you expect from the daughter of two gryffindor's? that being said, she would be the first to volunteer going into a haunted cave. yes, she's scared. heck, she would even take her broom and fly herself to another state if it weren't for her pride. she believes that she has a natural leadership which would make people follow her footsteps – but we all know it's not that case. in fact nobody would follow the path she paved. nobody would trust a ravenclaw who does something without thinking about its consequences. she's a very possessive person and doesn't likes to share what's hers; be it friends or things. she wouldn't express her disapproval if you got close to her friends. instead she would curse you to death in her diary. to add on, her possessiveness always lead to obssessiveness. no, not obssessed over some stupid animes. instead she would obssess over her crush. as sickening and creepy as it sounds, constance is like a stalker. "but a cute stalker... have you ever seen such a cute stalker?"

but let's not forget that human all have their sentimental sides as well. constance tends to get very violent and rash when she's angry. often she would try to resolve her anger by challenging the person (who caused her anger) to a wizard fight. of course, she's not that capable. she would definitely lose, for a record she has never win a wand fight at all. she's rash, she wouldn't think of the consequences and she doesn't have anything prepared to answer the headmaster when she gets into trouble. so much for her pride and rashness. constance tends to be very clingy towards the person she likes; a sign of obssessing. which often drives her crush away for not many guys fancies clingy girls, goddamn it it's 2015 already. playing hard to get is the trend. for a genius like hyesun, she sure is stupid when it comes to courting guys. when she's sad, she tends to distant herself from everyone and would always leave hogwarts without permission on her broom. she says it's because she wants some space, but mc gonagall just find the girl irresponsible and often threatened to expel her.

background: constance jin is the daughter of justin jin and hwang soyul, muggleborn. in other cliche plots, the female lead would always say it's alright that she's born a muggle and that she's still proud of it, but not for constance. she loathe that she's a muggle, she grew up and even witnessed the took placing of the hogwarts battle. sure, there was hermione – also a muggle; and was a very outstanding witch. but constance was sure she was nothing like that. being a muggle not only decreases her chance to outstand in her house, it would also make certain slytherins hate her. 

constance got into hogwarts when she was 11, and was initially sorted into gryffindor but was switched to ravenclaw when she was 12 for the sorting hat said that she did not believe in herself to be a fellow gryffindor.

close friends | yoon alice (oc) | 16 | hufflepuff's student | whiny, supportive, extrovent | alice is the person that constance spends the most time with; and talk to. she would always complain about how she dislikes bohye and that she's always near her crush while alice would roll her eyes and tell her that her crush is not meant for her but she still can give it a go
