While Rowoon was speaking in front of the class, he then invited Chani to perform the choreography of the song 'Good Guy' in front of members of 'Knowing Brother' and other celebrity guests.
The two then brought the choreography of 'Good Guy' so eloquently and compactly, that they received a standing ovation from the members of 'Knowing Brother'.
In addition to featuring the choreography of the song, Rowoon also showed his vocal abilities by singing the song 'Rain', while Chani showed his dance abilities.
