Jipil is a recently divorced man with no major flaws, just a few lingering emotional bruises. One night, after drinking a bit too much, he picks up a stray cat on the street and brings it home. But the next morning, the creature in his bed is not a cat at all. It is Myohyeon, a runaway catgirl with ears, a tail, and her own share of complicated circumstances. Memories of the “dream” he thought he had, the night he spent with her, suddenly come rushing back. Myohyeon insists he take responsibility and let her stay with him. Before Jipil can even argue, his friend shows up at the door. Panicked, Jipil introduces Myohyeon, in her cat form, as the pet he is raising. And just like that, living together becomes unavoidable. With a few ground rules set, the two begin an awkward but strangely sweet cohabitation. Can they follow the rules and keep life peaceful, or will the unexpected feelings between them break every boundary?
