Description

Is this an Error or Love?
Sangwoo Choo is just like an emotionless robot who only knows how to follow the rules. So after all of his teammates got a free-ride on the group project, he didn’t give them any credit at all. This prevents college senior Jaeyoung Jang from graduating, which leads to Jaeyoung constantly bothering Sangwoo for revenge. Will Sangwoo be able to debug Jaeyoung — a semantic error — from his perfect life?
