Han Seojin is a "cool beauty" and is famous for her looks at the university.
She has known Kim Jangin for 17 years.
She considers Kim Jangin just an annoying younger brother from next door and has no romantic feelings for him.

Kim Jangin has been the younger brother next door to Han Seojin since they were children.

...Hmph.
