Prologue

Seventh years of Gryffindor and Slytherin have always hated each other.

Nobody really knows what went wrong but somehow it is said that they have become sworn enemies since their first year. Since then, they have declared not to befriend each other and if anyone gets caught for being friends, they would get ostracized for life by the same years of their houses.

Despite the whole hate ordeal, two seventh years from the respective houses somehow have fallen in love with each other. In fact, the Head Girl of Slytherin, Sky Kim is actually dating the Quidditch Captain of Gryffindor, Sam Hwang.

Alternatively, the history of how Sky begins dating Sam.
