Breathless Summer is as much a social drama as it is a love story. Takei plays said girl who learns that her mother never recorded her birth in their family register. While falling into despair after finding out the secret about her birth yet wholeheartedly trying to live to regain "herself", she happens to run into a former journalist who is suffering from a deep scar in his heart himself. Although they could be father and daughter, they start to develop much stronger feelings for each other, a love forbidden by society.
