I once promised her that I would write down our story. I am very lucky to have met each other during our best time. "Love doesn't know where it starts, but it goes deep." Every time I see this sentence, I think of her smile, and my whole person becomes soft. We met when we were young, but were lost in the vast sea of people. We met again after many years and finally saw my own heart clearly. Maybe in everyone's life, there will always be a person who leaves a deep mark on you the moment she appears. Maybe there was a bright future in the past, but you can no longer escape or leave.
