Rosa is an emotionally anxious woman marked by traumatic experiences, which makes it difficult for her to form deep connections. She idealizes those who show her kindness and seeks comfort in romance novels, yearning for the love they describe, although she does not feel deserving of it. Despite her difficulty in sharing personal aspects, she enjoys social company and events, preferring to appear calm and humorous to avoid conflicts.

She comes from a religious and conservative background that demands purity, leading her to live a double life. At night, she escapes to parties in search of different experiences and maintains a light workload.

Rebellious and dreamlike, Rosa suffers from derealization and anxiety, being impressionable and compliant. Although she is charming with those she cares about, she struggles to open up to romantic relationships, keeping her encounters limited to affectionate gestures. Her desire for a free life conflicts with her need to maintain an image of purity, causing feelings of guilt and insecurity.

Although her relaxed and extroverted exterior contrasts with her vulnerable interior, Rosa displays a defiant attitude and ironic humor to cope with stress. She is self-taught and creative, having learned many skills, including magic. She tends to avoid direct confrontations and uses humor to deflect conflicts, hiding her true feelings behind a carefree facade.
