The Time Travel Was Broken, and I Didn't Even Know

My life was unremarkable. I never really enjoyed love and fell in love once, but my girlfriend also left me. It should be said that I pushed her away with my own hands. For this reason, I closed my heart and became a lonely person. In the end, I left in an ordinary way. However, God favored me and I was reincarnated in a different world.
