It's not horror, it's romance! The timid Angel lived in an empty villa and was rumored to be a female ghost. A scientific research professor who didn't like to get along with others bought the house and the two began to get along wonderfully. The angel didn't know that the professor could see him and looked at the good-looking "intruder" wantonly. However, in the professor's eyes, the angel was not the scary and weird soul that outsiders described him as. The unkind and cold professor and the timid and curious angel.
