Sister, if you like it, I will be your sword and eliminate your worries.
Sister, if you like it, I will be your little sister. I want your protection, support and encouragement.
In my previous life, you protected me;
In this life, please let me protect you.
I will always be loyal to you, my dear sister.
[This article is dedicated to my dear sister. Although I don't know if she can see it. ]
