Ahn Jiwon is a BJ (Broadcast Jockey) who is also the school president studying Consumer Information Science. As BJ Alex, he held a lot of charisma often times when acting out different roles while performing and telling sex-related stories to the audience. The reason why he started broadcasting in the first place was because he didn't want to feel lonely and he desired the attention that was not given from his parents.

Jiwon has wavy black hair that's often styled during his BJ streams. He has yellow eyes and pale skin, as well as a ripped body his viewers on NutworkTV love in addition to a birth mark on the left side of his stomach. Because of his family background, he wears expensive brands to school and for casual wear. In some of his streams, he talks about having a mole on the left side of his neck which he attempted to remove, but could not because it kept on reappearing. While broadcasting, Jiwon wears a black, white, and yellow mask which covers most of his face.

Meeting Dong-Gyun, Jiwon did not want to have sex with because he was a virgin. This was because of the incident that happened when he was a naïve teen. He lost his virginity to his older brother's best friend and did not want to be the bad guy to take away someone's virginity. Myung-Dae and Jiwon have not done anything sexual. When Jiwon is around Myung-Dae he often acts annoyed and occasionally flustered.
