Masaki, an omega, and Hiromu, an alpha, navigate the challenges and joys of their family life while addressing societal expectations and personal struggles tied to their identities.

Masaki, a homemaker, dedicates himself to caring for their son and managing household responsibilities, often reflecting on his past experiences as an omega in a society that traditionally marginalizes his secondary gender.

The couple’s dynamic is further enriched by their interactions with extended family and friends, who provide additional layers of support and conflict.

The narrative explores themes of family, acceptance, and resilience, emphasizing the importance of communication and understanding in relationships. Hikari, their son, serves as a focal point for many of the series’ emotional moments, as his parents strive to create a nurturing environment for him while confronting their own insecurities. The story also delves into the broader omegaverse context, addressing issues such as gender roles, societal prejudice, and the complexities of navigating a world where biological traits heavily influence personal and professional lives.
