E.X.ing is a new kind of an odd relationship between grown man and grown woman who used to be a lovey-dovey couple but ended up hating on each other because of a childish break up.
Luhan and Sehun had hated each other ever since they first met. They don't know why they hate each other. They just do. Just looking at the other could send their blood boiling. But, what happens when feelings start to change through a stupid bet and unfortunate events?
