Sera is in a relationship. Hyuna is jealous, she only wants Sera. With a few other members trying to steal Hyuna's heart for themselves, Hyuna has to keep focused on what her mind and heart both want but there are many distractions and obstacles.

Hyuna sat down on the floor to get a drink of water and to rest a bit. She watched as Sera and Kyungri play together. Sungah sat down next to her.

"Hi unnie!"

"..Hi Sungah.." Hyuna mumbled as she watched Kyungri and Sera hugging tightly.

"What's up with you?" Sungah asked, frowning.

"Nothing. I'm just tired." Hyuna said.
