Sana and the other members—Nayeon, Jeongyeon, Jihyo, Dahyun, and Momo—are all in the same group. Sana often goes out in the evening to meet a person who is an old man that helps her gain visibility because he has connections. Tzuyu is a vice president at JYP Entertainment. She and Sana have gotten into fights frequently, and Tzuyu forced Sana to join a show that requires extensive knowledge. At first, Sana disagreed, but she had no choice as Tzuyu could fire her. In the end, she agreed, and Tzuyu tutored her until Sana realized she had fallen in love with Tzuyu.
