A burnt-out office worker suddenly transmigrates into Seraya, a woman known for cruelly torturing her beast husbands in a spirit forest world. Seraya faces immediate danger as her four spirit beasts, previously forced into contracts, overpower her due to her weak F-class Soulbinder status after her powerful mother vanished. She unexpectedly gains a bond with the Spiritual Power Refund System, which will boost her strength by refunding spiritual power spent on healing her beasts. Her first mission is urgent: within five minutes, she must choose and heal one beast husband or risk losing her soul. However, the beasts resist her help, blocking her efforts and escalating the threat.
