She's Scary Manhwa

From Loyal Kiss:
A beauty at first glance,
the opposite of organized,
Swearing as part of her daily routine,
The so~ hot girl, Jin Eun Jung
Considered a hunk by everyone,
A textbook example of a good student,
The king of organization,
The student council president,
The so~ hot guy, Moon Seo Young
Suddenly one day,
these completely different people
start living under the same roof
and something starts to change!
In a bittersweet way ?
A hot bad-mouthed girl just lost her wallet, determined to get some money, she sees a guy walking down the street, brings a stick and asks him for money, Moon Seo Young, the oh-so hunky goody two-shoes, whose money just got robbed by a girl. how uncool~ but, he has to forget about that since he has much bigger problems cause, Jin Eun Jung, who happens to be that girl, is gonna start living in the same roof as him. woah~ She really is scary. This must be a dream, right?
