Hate Me Now, Love Me Later

Jhun was only a plain senior college student until she met a former highschool classmate who happened to be a newly-hired instructor to their university. For four years being classmates, they were even barely talked. They were not friends but neither enemies so.. what will happen if their paths collide after five years? Will they get closer this time? Will they become friends? Or more than that.. PS. Will come up with a better synopsis and book cover next time :)
