A plan for a story

When he arrived at a place, he meets lots of new friends that he had never met before until he finally saw a honey blond girl in his sight. Although, she was different than the rest. Very different. Her attitude wasn't heartful, it was heartless than ashes.

What will happen between these two strangers? Will love come first at their peak? or death?
