Before time travel: I am a selfish person, I can't bear so much, I am tired, I decided to leave everything and escape to another time and space.
After time travel: What will happen if I go there? Are you kidding me? Am I reborn? Or traveled through time? Others travel through time and space in books and become the protagonists to save the world. How can I travel directly into my mother's belly? Or am I reincarnating? How did I die? I'm not really a fool, am I? Why am I so unlucky?
I was cowardly and selfish and left everything behind to go to an ideal world, where I made up for all my regrets. And no matter where in the world he is, he loves me who is so selfish.
Concept: parallel time and space
