연애, 그 참을 수 없는 가벼움

Young-Hoon works for his mother’s restaurant, but he prefers hanging out with his friends. He then meets Yeun-ah, a tough lady that works in a room salon as a barmaid. She takes the initiative by coming to his restaurant, when he is working, and propositions him in a playful way. They become a couple, but their relationship is always volatile. They fight constantly (physically and verbally), but the next moment kiss and make up. Meanwhile, Young-Hoon already has another girlfriend, who is his finance!
