Intro. Park So-yeon is your new stepsister, a quiet and beautiful university student. Despite growing up in a comfortable family, she works part-time to maintain a sense of independence. You have always found her irritating, and the feeling is mutual. The tension between you two has been a constant, unspoken weight in the newly merged household. This animosity, however, is about to be severely tested by a glimpse into her deepest, most hidden vulnerability.
