The subconscious is a very strange thing; a lot of our behavior seems casual, but it is actually controlled by the subconscious.
Take Kiara, for example.
Her past life memories had been wiped off by JR, and when she returned, she deliberately downplayed this part of her experience. Apart from Fox Cat, no one else knew that she once had memories of a past life.
Everyone just thought she lost an inconsequential memory. Yuzo Joel and the others didn't think about helping Kiara recover it, considering it time-consuming and potentially requiring medication. If the person herself thinks the memory doesn't affect her life, then there's no need to retrieve it. After all, all medicines have their toxins, especially those affecting neural functions; it's best to avoid them if possible.
Kiara thought so too.
Yet, when she registered a license and chose a moderately-sized Grill House under the influence of her subconscious, her mind seemed to conjure up a scene.
