The Witcher: Minimalist Journey

Is a time-traveler who only has the memory of the time-traveler still a time-traveler? Does Klein refer to Klein blue or Klein bottle? "Is my life a cheat?" "I can't see anything bad at all. All I see is beauty and harmony." "This is a scene that can only be found in fairy tale books!" "Why do I feel more and more like the world revolves around me?" "Hey, there can't be any conspiracy, no, I have to check the situation again." "Speaking of which, I'm not the protagonist who competes with the air, right?" "Forget it, I don't want to think about it anymore, my life of inexplicably switching to minimalist mode has begun."
