Six months after Juanito's birth, María struggles with postpartum blues, while Gari sets out to get his driver's license; Cris and Pablo consider spicing up their newly recommitted marriage.

At therapy, María laments feeling trapped in an unfulfilling life while everyone around her seems to be moving forward with theirs; Cris and Pablo navigate the reality of open boundaries; Esther and Júlia's visions for the future start to clash.

Esther takes a job to avoid Júlia; Gari fixates on the outcome of his driver's test and news of María and Xosé's rekindled flame. As Cris begins to bend the rules of the sex contract, Pablo grows increasingly wary of their arrangement.

As he becomes more involved in María and Juanito's lives, Xosé's deep-seated feelings towards parenthood bubble to the surface. Cris further explores her connection with Álex; Júlia attempts to immerse herself in her fiancé's world.

Esther abandons María and Cris on spiritual retreat, leaving María to surrender herself to healing while Cris obsesses over Álex. After helping Gari and Mónica rescue a wounded bird, Xosé gradually finds himself back in Gari's good graces.

On her wedding day, Esther faces a choice: take a chance on marriage with Júlia or act on the fear rooted in her gut; Cris is forced to confront the state of her own marriage; María contemplates the future of her relationships.
