Sometimes we encounter very painful moments and meet a stranger at a very special moment. My only love tells us four different relationships in the omnibus form—growing while untying the heart knots of life to understand more, facing the forgotten past to open the eyes to a new life, preparing a farewell with one who lost the memories, and giving hopes for the left even at the moment of leaving. These four stories about relationships linger in the heart for a long time after. [CHOI Jina]
