Why would a woman who has it all simply vanish without a trace?

In I Thought I Was Happy (Creía que era feliz), Susana Gisbert Grifo constructs a gripping psychological puzzle around the sudden disappearance of Inés, a young woman with a seemingly perfect life. When she vanishes, leaving no clue as to why or where, the facade of her flawless existence begins to crumble.

The story unfolds through the voices of those who knew her—friends, family, and acquaintances—who step forward to share what they know, and perhaps more importantly, what they don't. As the stereotype of perfection fractures, the investigation reveals the hidden cracks in a life that was "wonderful" only on the surface.

While the search for Inés drives the plot, the true mystery lies in the past. This is not just a story about finding a missing person, but an exploration of identity and the breaking point of the human spirit: how and why did she reach the moment where disappearing was the only option?
