The Sweetheart's Cat-Petting Technique

Blurb:

At the entrance to Reincarnation Lane hang two shop signs. The first floor is the irresistibly flirtatious Sweetheart Pet Hospital; the second is a quaint shop that buys antiques and old things. The endlessly chattering, foul-mouthed cat shopkeeper, the proprietress who grows a tail whenever she gets angry, and the half-baked veterinarian who always makes lovestruck girls scream take in antiques, old objects, and spiritual energy. But what they collect most of all are... supernatural beings among humanity.

The hot-tempered, incredibly tough heroine, the proprietress, vs. the gentle veterinarian hero, whose magic works only now and then.

One-on-one romance, happy ending. Sweet, swoony, and satisfying.
