I am a traveler through time and can go back in time. Can travel to the future. I can see people's pasts by touching them, and I can foresee their futures. Many times, whenever I saw the tragedy that was about to happen to them, I couldn't stop it. I can only act as a simple passerby. But when I met him, everything started to change. . . . . (I want to write a warmer and healing story. It's my first time writing, so please forgive me if it's not good.)
