The two actors go through several takes to get the kiss scene from different angles. In one of the cuts, Hong Jong-hyun awkwardly laughs when YoonA says she can't breathe. He can also be seen fixing YoonA's hair whenever the wind blows it into her face. Hong Jong-hyun then comments that he can smell YoonA's scent even whenshe's away from him.
You'll definitely be smiling throughout the whole video!
