Seongshik Oh

Seongshik Oh (Oh Seongsik 오성식) was a professor and counselor at Yonggang University before Professor Frost replaced him.

Appearance
Seongshik Oh is a dark-skinned man with dark blue hair and a tired face.

Personality
Seonga states that Professor Oh may have been careless, but was a good person. Frost agrees that he would smile at everything.

The Empty Man
Seongshik sits at his desk, extremely bored by the lack of students coming to see a counselor. Seonga helps him, and Seongshik says that he pities her for having to stay around in a stuffy office with him. He states that he wishes he were to be in a lab writing dissertations instead of waiting for nobody, which annoys Seonga. Just as she is about to start retorting, he reminds her that she has a class. As Seonga leaves, Seongshik wishes that he could leave too.

When Frost arrives at the university, he asks Seonga if Seongshik is there, and Seonga responds that he'll be gone for the day.

Ten Days of Shy Mr. Yeon
Professor Oh is sleeping when Seonga barges in and asks for the list of students from his previous class. It turns out Professor Oh is the teacher who ridiculed Jaeon in his first semester and caused his anxiety to flare up. Professor Oh assists in collecting the papers for the longitudinal study that Professor Frost and Seonga conduct.
