Yoona & Seohyun are best friends that have been close since they were kids. While different in their own ways, the pair share a strong bond that has only gotten more resilient through the years. Now in their final year of highschool, the two come to the realization that they will be going in different directions in life after graduation. Seohyun has ambitions to head to the Ivy League, while Yoona doesn't really have much ambition at all. Acknowledging the fact that Seohyun will be seperated from her in a years time makes Yoona more upset than she expects. She soon discovers that she has feelings for her best friend, which makes the prospect of Seohyun leaving her life horrifying. It's not long until Yoona desperately searches for the right way to convey her emotions before her best friend and love interest leaves for good. She finds herself chasing after a girl who has never really experienced dating or love, someone who hasn't even had a first kiss - miss innocent. Things get even more complicated as Seohyun's other admirers join the fray, who are equally determined to win the girl over.
