Chapter 1. Meeting him

You were walking on a nice warm summer night. You stop seeing a tall shadow. He approaches you. You stop to see his hand holding out to you. You smile and shake his hand.
"Hello there my names gaster sans but you can call me g." He said shaking your hand.
"Hello there my names [y/n]"
"[Y/n] thats a beautiful name" he said smiling his smile was so beautiful it could light up a room. You stop shaking his hand and smile.
"It was nice meeting you g" you say happily.
"It was nice meeting you too
[Y/n]" he says also happily.
You blush just looking at him.
