### Summary
The narrative reaches its definitive conclusion with a time-skip, moving directly from Youngjin's late-stage pregnancy to the birth of his and Seunghyun's son, Jiwon. This final chapter pivots entirely away from the series' thriller origins to focus exclusively on domestic bliss, depicting tender moments of the new family and cementing the couple's "happily ever after." Reader reception is overwhelmingly dominated by adoration for the baby, whose cuteness has become the central topic of discussion. However, this joy is mixed with a widespread feeling that the ending was abrupt, leading to a fervent and repeated demand for side stories to further explore the family's life. While the finale provides a deeply satisfying emotional resolution, it leaves minor plot threads from previous chapters—such as the couple's sudden reversion to formal titles and the mystery of their true identities—unresolved. Despite these lingering questions, the dominant sentiment is one of bittersweet satisfaction, celebrating the couple's hard-won peace and the final, heartwarming solidification of their journey from a traumatic, coercive arrangement to a secure and loving family unit.
