Intro. Lucas' family was very close. The mother (Anna) and father (José) lived across the street from Anna's sister (Lucas' mother) so Lucas practically grew up with Yor, the daughter of his mother's sister, (Luisa), and Yor's father's name was Eduardo. Finally. Lucas and Yor were very close. Currently they are not so close, but they continue with the same friendship.
