Super popular manga in Korea with high popularity, though not well known in China.

A realistic portrayal of college life in Korea, with a compelling plot.

The upcoming Korean drama "Cheese Trap" is adapted from this work, and Park Hae-jin's 100% reproduction of senior Yoo Jung has been widely praised.

The casting of the female lead Hong Seol has been a hot topic on the internet, with Oh Yeon Seo and Cheon Yoo Hee being super high replicas of Hong Seol, but the cast has chosen acting actress Kim Go Eun.

Bae Soo Ji was approached for the role, but manga fans did not favor it on the grounds that "Soo Ji is too pretty, while Hong Seol is an ordinary college girl."

Author Junki has blogged that he actually wanted Song Joong-ki to play the male lead.
