That year, the spring breeze was just right, and we fell in love with each other. Later, I promised to change someone, and I tried it, but I couldn't forget it and couldn't get rid of it. It was like a scar, always there. The knot you left for me is that I can't accept others and can't get out of it. In fact, I have always wanted to accompany you, but in your world, I am just a guest.
Purpose: Remember our past
