Enrique Ramos Villarán (November 13, 1984) is a 30-year-old doctor and oncologist from Huelva. A single man, he considers himself romantic, home-loving, honest, distrustful and stubborn. When he entered the house on Day One, his secret remained undisclosed to the audience. In the following weeks, the program revealed that there was a competitor who was considered to be expert in Big Brother. In the last assembly of the secrets, Enrique confessed that he was the expert and that he had watched Big Brother of Spain and of other countries. Many spectators and also many contestants were thinking that he had some type of kinship with Carolina. In the week three, he gained the immunity and he wanted to liberate Han of the nomination instead of himself, invoking that he wanted to face Suso in nomination. He was the fourth evicted on Day 33. He tried to return to the contest and he lived in the apartment with Maite, Raquel and Muti until he was eliminated as a third option chosen by the audience.
