My sister is bound to the "stealing life" system in order to become me and gain my life. Just out of jealousy of me, jealous of everything I have gained, the choices and systems I've made a deal with. But everything I did was done through hard work, and I never neglected it. As a result, I died unexpectedly in my previous life. I will definitely not let such a thing happen again in this life. Since she likes my life, let her take it.
