Yeonjun's childhood was difficult, his father beat him all the time for small mistakes. Time passed, and the scars remained as a reminder of the past. Yeonjun found a job as an English teacher, the children loved him very much, as did his colleagues. There Yeonjun met Soobin, they became good friends. Although Soobin taught children literature, and Yeonjun taught English and they were both different, they managed to find a common language. It was evening, Soobin was sitting checking the students' tests, as was Yeonjun. Both were sitting in peaceful silence when suddenly someone bursts into the door.

"Where is that little bitch?!"

A scream is heard, Yeonjun freezes recognizing this voice out of a thousand. His father is here.
