Being a patrolling demon in Langlang Mountain is just a job, at least that's what Agua, the crow spirit, once thought - until he unexpectedly gained the strange ability to eavesdrop on people's voices. The calculations of his boss, the hypocrisy of his colleagues, and the ulterior secrets of those "goddesses" with different thoughts poured into his ears like a tide. Performance review? Nepotism? Workplace strife? In this evil-minded Langlang Mountain, the truth is often more hurtful than magic. Forced to deal with the shrewdness of the white rabbit, the charm of the red fox, and the arrogance of the golden pheasant, Agua discovers that if she wants to live safely in this world where the big monster is king and the little monster fishes, it is not enough to patrol the mountains. She also needs to have some special "hearing" and "speaking skills." This is an alternative history of how a low-level crow spirit managed to make a comeback in the gap between the workplace and the love world by relying on his gossip.
