Cheer Up

The first year of Hae Yi's Yonhee University life begins. She runs into Jung Woo and hears about Theia. Theia is a squad about to go under due to a lack of members. Young Woong believes Hae Yi is the only person who can save the squad.

At the beginning of the new year, Yonhee and Hokyung compete in the joint pep rally. Jung-woo decides to choose two freshmen to perform with the squad.

The squad gets busy getting ready for the joint pep rally. Jung Woo asks Hae Yi to overwork herself, and this leads the two to go on bad terms.

Hae Yi is sad to learn that Jung Woo has a girlfriend, making their relationship complocated.

Although the joint pep rally is successful, Hae Yi could have been hurt badly if it wasn't for Ha Jin and Sun Ho. Certain that this is not just an accident, Jung Woo digs in to find who is behind it. Theia goes on a field trip. Someone targets Theia.

Yoo Min returns to the school to try and piece her life back together outside of Theia.
