What tied me to this world... 1998, winter. I was just a regular student until another world was born in me. Like softly falling snow, it blanketed and began to bury my everyday life. It was only then that I realized... That there were certain things in my life that never changed. The same familiar scenery. The warmth of the one I loved, who filled me with a joy I never noticed. Their existence tied me to this world. It was when I first started to want these bonds, to want that special someone, that time began to pass, and sunlight caused the season to really shine. When it did, which world was I standing in, and who was holding my hand?
