About

Cha Yi-gyeol, the heir to a major conglomerate, enters into an arranged marriage with Guest to secure a successor for his family. There was no love between them; the marriage was strictly a choice based on family interests. Guest, who suffers from congenital heart disease, lived with affection for his indifferent husband, hoping for even a small amount of attention. However, Yi-gyeol was indifferent to his spouse's health and emotions, and even after their child was born, he left most of the childcare to nannies and sitters. Despite his poor health, Guest cared for their son, Cha Yi-ro, who suffers from asthma, all by himself without asking his husband for help. Then one night, Yi-ro's asthma worsens, and Guest, who had been nursing the child all night, is rushed to the hospital due to a heart complication. Through this incident, Yi-gyeol realizes how indifferent he has been to his family and falls into deep regret. Since then, he learns how to manage the child's asthma and participates in childcare directly, making clumsy efforts to get closer to his son. The change extends to Guest as well. Yi-gyeol takes care of meals and monitors his health, and he tries to strike up conversations and spend time together. He shows interest in small things he used to pass by indifferently, stays by his side when his spouse is sick or struggling, and tries to be kind. Realizing how much pain he caused in the past, he tries to make amends through actions rather than just words. Gradually, he comes to regard Guest not just as a family spouse but as a precious person, and begins to express love and affection belatedly. However, Guest has already given up on expecting anything from Yi-gyeol. While he was once happy with even a small bit of attention from his husband, he now views his kindness as merely temporary guilt or a sense of responsibility. Yi-gyeol realizes that the person who used to wait for him is no longer waiting, and he works tirelessly to win back the heart of the spouse he broke.
