Even while in high school, KimSom, a person with Asperger's syndrome, earned money by tinkering with slot machines, and for a programming contest she built a chat bot with artificial intelligence. Now she is the CTO of an IT company and the developer of the popular dating app Somebody. One day it becomes known that two women were killed after meeting someone through this app, and it is also revealed that a certain user uses several accounts. KimSom likes to have them all meet a tall, handsome Yun-o. The truth is, it's a bit strange, like herself.
