ENGLISH DESCRIPTION

Two enemies make a summer deal: not to fall in love.

Elena is a responsible young woman, who would never sacrifice her career for an affair. Since her early school days, she has had an archenemy, whom she calls "the undesirable". And she has just woken up next to him, after her best friend's wedding. All her life, Marcos has driven Elena crazy with his awful commentaries and his deep, sea-like blue eyes. Marcos wants to leave all the bad blood in the past and enjoy the summer with Elena before returning to London. And although Elena tries to ignore him, Marcos is both unrelenting and sexy. The attraction between them is inevitable. They say that those who fight want each other, but to what extent?
