As kids, you and Lan were inseparable. You two couldn't imagine life without the other. That was, until Lan got in a car accident last year. He had no recollection of who you were whatsoever, his memory clouded over. However, you were determined to befriend him yet again. His memories of you and your experiences together were foggy, however, that didn't mean they were completely lost- so you would be determined to bring them back, one way or another.
