Lin Zhuzhu's favorite thing to do since childhood was to bully and tease her younger brother. When I grow up, my hobbies are watching handsome guys become infatuated and reading some pornographic porn~
Lin Yuanlan has liked to follow her sister since she was a child. His sister would fiercely stand up for him when he was bullied, and would fight with others and get into a ball. When he cries, he will fiercely say to him: Why are you crying? As my younger brother, Lin Zhuzhu, your future goal is to conquer the stars and the sea, so I put all my hopes on you. If you cry again I will ignore you from now on.
From then on, he really didn't cry again, he just thought that he would be the one to protect his sister in the future.
But then my sister died. It was him who failed to protect his sister. For a year after his sister's death, he had been living in a state of confusion, when he finally avenged his sister. He is also dead.
Then he was reborn.
In this life, my sister belongs to him only! He will nip all dangers in the bud, and all those who covet his sister will die! No one can take his sister away, not even death can separate them.
