Shea Yeoman, a gentle and family-craving 14-year-old girl, was adopted by a family due to a family tragedy and became “siblings” with Chad Church, a peer of the same age. Chad, with a cold and detached personality, having grown up in the shadow of his parents’ divorce, was filled with hostility towards Shea who suddenly entered his life. Therefore, he always treated Shea with coldness and deliberate distance, even avoiding her at school.
