[3] The film is adapted from the first webtoon by Kang Full,[4] which was serialized on Daum and attracted a record-breaking 60 million page views and 500,000 visitor comments.

[7] Hello, Schoolgirl was released in South Korea on November 27, 2008, and topped the box office on its opening weekend with 309,065 admissions.

Joon Soh of The Korea Times praised the film for retaining the essence of the webtoon despite deviations from the original story, saying, "Ryoo succeeds in capturing the tenderness of the online comic, which slowly comes to the surface as the relationships unfold.

There is a rich, layered quality to the film, where each little decision or gesture leads to further meanings and possibilities"; however, he also noted that "there are times when the movie aims too much for the conventionally beautiful, sacrificing the awkward, self-deprecating humor that drives much of Kang Full's works.
