A spoiler about Aster's ending
Spoiler!
After killing Lianca, he decided to go back to the mansion because he was injured (Lianca had stabbed him in the neck after her first escape, and this time she punched him too and he was also half-blind). The medicine was wearing off, so when he was going back, somebody pushed him and he started rolling down a small mountain. He grabbed a small branch and was holding on, but somebody crushed his hand, so he went bye-bye and drowned in the same river where Leticia was pushed.
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule
