"Advertisement Genius Lee Tae Baek" Han Sun Hwa becomes a member of a girl group even in the drama.

March 25, an episode of the KBS drama "Advertisement Genius Lee Tae Baek" featured Lee So Ran (Han Sun Hwa) preparing for her debut as a member of a girl group.

Han Sun Hwa somehow begins selling items for a corrupted religious organization and even shows up to her brother's work place, Giants Advertising Company. People mock her about her situation and make sarcastic remarks.

When Ma Jin Goo (Go Chang Suk) sees her, he says, "I'll buy everything you have so keep this a secret from your brother." He then pays her $3,000 for all of her items.

When she finally escapes the organization after selling all of her items, she decides to become a member of a girl group. Lee Tae Baek (Jin Goo) asks, "Are you really going to do that? Is that really a reliable company?"

Lee So Ran replies, "Not anybody can do this. I can do it because I'm not anybody." Whenever people asked about the name of the girl group, she told them it is a secret.
