Fantasy Is Also a Kind of Life

Regret always runs through our lives It's me now, or you in the past, who always think about what would happen if this wasn't like this, what if it wasn't like that. Is there really a parallel time and space? Is the so-called time travel and rebirth a regretful filling of the gap between the current me or the current you? Can we not travel back and forth, but let's see what kind of magnificent life our other selves in parallel time and space can have by taking a completely different path, haha
