Vinicius Hwang, a mixed-race prodigy with an IQ of 190, was diagnosed with Antisocial Personality Disorder (ASD) during his teenage years. At the age of 23, he is about to complete his Ph.D. and take over as chairman of the HK Group. Detached from everything that involves relationships, Vinicius is devoid of feelings such as empathy, pain, anguish or love. However, something changes when he meets Julia, a young Brazilian woman who has entered the arts course at Seoul University. Surprisingly, Julia is the first person to catch the billionaire's eye, leading him to see her as someone who can satisfy his instincts. Julia, for her part, is a beautiful, intelligent and talented gaucho who has decided to study in South Korea, also seeking to reconnect with someone important from her childhood. Although initially suspicious of Vinícius' approach, after a great discovery, Julia ends up falling in love with his beauty, charm and intelligence, and begins to experience a mixture of love, gratitude and hurt with him. In this scenario, the question that arises is whether Julia's enlightened personality will be able to break through the complex barrier of Vinícius' dark mind. Will she have the power to awaken genuine feelings in him and transform his view of the world?
