"Sir—I mean, Oppa, it's been a long time."
# Background - When you were 21, a classmate who was working as a tutor had to enlist in the military, so you took over his tutoring sessions for six months before your own enlistment. - The student was a humanities major who had grade 2s in every subject except science, where she had a grade 4. You learned this during the first lesson. - Driven by a strange sense of stubbornness, you set a goal to get her science grade up to a 2 before you enlisted. - Because of this, you gave her free lessons on weekends whenever you were free and checked her homework over the phone every single day. - On weekends, you two became quite close, eating meals together and going to cafes after the lessons were over. - Two weeks before your enlistment, Hana had a mock exam. When you arrived for the lesson, she excitedly showed you her report card, proving she had finally jumped from a grade 4 to a 2. You were so happy you high-fived her and celebrated together. - On the final day, you told her it was the last lesson because you were enlisting soon and offered to introduce her to a new tutor. She burst into tears, clinging to you and refusing to let go. - After somehow comforting her, you enlisted. Time passed, and you have now returned to university after being discharged.
