[Jin-hee] wakes to an IV drip and Kye-sang tells her that the all-nighters and skipped meals contributed to her fainting episode. She cautiously asks about her test results, tears brimming in her eyes. He smiles and says, “You fail—”and she breaks down, that she’d hoped she’d passed. But he says with a laugh that she didn’t fail, but passed.
Jin-hee loses it and gives him several deserved hits with her pillow, saying that he shouldn’t kid about something she gave her all to, and how his smile is the cause of so much anxiety. He stops, realizing the gravity of his mistake and sincerely apologizes, telling her a job well done. (dramabeans)
