After years of wavering between love and friendship, Rina and Ren finally begin a new chapter as a couple. While raising her daughter as a single mother, Rina decides to pursue the Certified Public Accountant qualification in order to build an independent future, and Ren does his best to support her. However, insecurities rooted in their pasts and their reluctance to burden one another gradually give rise to small misunderstandings. As they balance love, work, and family, the distance between their feelings begins to grow.
Following the events of the previous episode, a subtle rift develops between Rina and Ren. Although their feelings for each other remain unchanged, past emotional scars, personal insecurities, and Rina’s determination to remain independent prevent them from expressing their true thoughts. As they each face challenges in their work, family life, and relationships with others, they are forced to reflect on what truly matters to them and what they want for their future.
