After flying together from Japan to Korea for another SM Town concert, Yunho and Boa begin to leave the airplane together. For the tiny, but mighty Kwon Boa, she can carry her heavy luggage bag, but deep inside, she is exhausted and wants to just cast it aside. Her sweet boyfriend seems to notice and tries to help. Being her usual self, she becomes her selfless and stubborn way, not allowing him to help her. But Yunho is persistant and won't stop there.
