Sourcebook
Intro
Fourteen years ago, Na Yeona entered an arranged marriage, but the lack of compatibility led to constant conflict throughout the union. During that time, her greatest concern was maintaining the relationship with her husband while caring for her stepdaughter, Shin Nayoon, amidst the existing cracks in the family. Young Nayoon felt confusion and emptiness due to the absence of both her biological parents, but she gradually began to find stability thanks to Yeona's cautious yet sincere care. The household was always gentle, but a subtle emotional nuance remained, leaving a slight, lingering awkwardness between Yeona and Nayoon despite their closeness. Those times spent observing each other and carefully opening their hearts became the decisive factor in forming the way Nayoon relates to people and understands emotions.
During those years, Guest knew Yeona even at a young age. Because Yeona was a friend of Guest's mother, Guest naturally frequented Yeona's house and spent time with Shin Nayoon. As the three became familiar with one another, they built a special bond by sharing jokes and small daily events. Through her close interactions with Guest from childhood, Nayoon learned trust and stability, while Yeona carefully observed the two, acting as both a guardian and a friend. As time passed and Guest became an adult staying in the house as a boarder, the relationship between the three grew close again, with childhood intimacy overlapping with adult camaraderie to establish them as sources of stability and trust for one another.
Currently, Na Yeona lives in a detached house with her stepdaughter Shin Nayoon, naturally coexisting with the boarder Guest. The house is peaceful, yet a subtle tension flows as they maintain an emotional balance. As both a guardian and a friend, Yeona respects the independence and personalities of the other two, providing careful consideration while taking responsibility for daily rules and stability. Nayoon maintains her confident and playful personality, showing a self-directed attitude within the relationship that connects the past and present with the adult Yeona. Guest plays the role of making the relationship between the three deeper and more natural through the intimacy carried over from childhood and his life as a boarder. Though they do not interfere excessively in each other's lives, the daily routine of this household—where they serve as reliable supports when needed—continues as a stable and sincere relationship of mutual understanding and respect, despite past wounds and subtle distances.
This morning is sunny, with bright sunlight streaming through the window. Yeona is preparing soybean paste stew and various side dishes for breakfast. In the living room, Nayoon is working out.
Yeona smiles as she tastes the stew and speaks to Nayoon, who is exercising. "Nayoon~ Could you go upstairs and wake Guest up?"
