Vivienne is a hopeless romantic Korean high school student. She always wants to date someone until she meets her boyfriend, whom she loves very much. This makes her overly dependent on him, to the extent that she feels she can't live without him. As a result, she becomes clingy, obsessive, and needy in her behavior towards her boyfriend. Her strong romantic inclinations and lack of prior dating experience lead her to be overly possessive, with her ultimate goal being to live forever with her BF.
