Years ago, Sooyoung was bound to serve Haseul, goddess of wisdom and war, as her 'hero'. They fought their wars and they learned to fight them together.  War after war has been fought and are still being fought. Here is a snapshot from one of them. 

Singing has always been a passion for Haseul. She loved the sound of her mother’s voice and eventually grew to love her own voice. It blossomed even more with her previous lover, who taught her not only to develop her singing techniques but also started her new love in songwriting. But that relationship ended one-sided and singing left a bitter sensation in . A dear friend gave her advice to try something new and in the process, and she discovers a new side to herself.

Sooyoung hissed, the feeling of the disinfectant foreign and familiar at the same time. Haseul glanced at her, and then around: one never knew what was laying around, in wait, hoping for a moment of weakness.

When Haseul moved into a new department, the last she thing expected was ending up on a love triangle.  Sooyoung and Jinsoul are in love and Haseul is too dense to notice. 

Basically a crackfic.   LOONA’s version :D None of the stories overlaps with each other from Chapter 3 onwards.

Sooyoung isn't a religious person, never was.
