Here's the report card of our friendship.
Three high school students, Jung-hee, Min-young and Sanna officially end their acrostic poetry club to focus on their college exams. The next year, three girls try to resume the club, but the distance and time difference block them. One day, Min-young invites Jung-hee to her flat in Seoul. Jung-hee is excited to spend time with her old friend but contrary to her expectation, Min-young is busy sending mails to her professors to get her grades corrected.
