Park Nari is a simple girl with a simple life. At least that's what she wants.

Her days are full of prickling fear and sickening guilt, but not for what you would expect. They stem from the most unlikely suspect, older people. No, not grandma's and grandpa's, though they probably frighten her too. No, this means anyone. Any sunbae, any oppa, any unni. Any ahjumma, any ahjussi. For some strange reason, she turns into a nervous mess around them. Which makes it that much harder for her to enter her first year of high school.
