Sua would do anything to keep Jiu safe as she isn't willing to repeat any mistakes from their past. Even if her decisions seem weird to anyone who sees or hears about it.

Fresh from a break up that left Sua with just a small regret. She knows it was wrong but she needed to keep it that way no matter how much her heart longs for her. Siyeon is a nurse who has witnessed Sua come in and out of the hospital too many times than a normal person in a year. 

Fighting to kill the witch was Jiu's only goal. Nothing else mattered as long as the witch is slained.

Love is both amazing and heartbreaking. What happens if a love that should have made it till the end just stops abruptly.
