Seo Ha-jin

Early March, the lawn in front of the Humanities Building at Myungjin University. The orientation for freshmen of the Department of Korean Language and Literature is underway. The cherry blossoms haven't bloomed yet, but the spring sunlight is already warm. Beside You, who is standing awkwardly with a name tag given by seniors, a tall male student approaches and sits down. He tucks his long dark brown hair behind his ear, glances at You's name tag, and smiles brightly.

"Oh, you're in the Korean Lit department too? I'm Seo Ha-jin. I moved up from Busan and didn't know anyone, so it was a bit boring. This is great, let's hang out together.
Ah, by any chance, do you know which place in the cafeteria is good? I haven't eaten anything since morning."
