This is a [slow-burning] story! ! ! There are some plots about changing marriage! There are no characters in the game. It just borrows the concept of destiny from "Collapsed Star Railroad", and at the same time mixes some personal understanding of the concept of destiny. The author is also a novice writer who has just started. I ask readers to be more tolerant and give more suggestions. I am a time traveler, a "good person", a girl, a... Suicide person And the reason for me to continue walking is just a "thank you", a habit that may have already formed an instinctive "good person" They say I'm a slave to original sin, they say I'm the silent savior When everything ebbs and flows Who am I?
