Doctor Chi leads a steady and joyful life with his son and wife, Ching, until he meets Yu in a birthday party. Yu falls in love at first sight with Chi and they have a one-night stand. Chi feels guilty for his betrayal as he is always so faithful to Ching. One day, Yu pays a visit to Chi's clinic. Chi thinks that they are about to let bygones be bygones so he does not mind to have dinner with Yu. However, Chi's behaviour gives a false impression to Yu and she thinks that Chi is interested in her. Yu believes that Chi is the destinated one and tries hard to get close to Chi's family, threatening their life... so she could be with Chi.
