Four years later. Eui Ju is now in her final year of university and has quietly built a name for herself as a successful novelist. Her life has moved forward-stable, independent, and far from the confusion of her school days. She always thought Mr.Ga would return after his short stay in the US. But he didn't. Instead, he comes back to Korea after four years... as a scientist. The school remains the same, with only a few of the original teachers still there. The past feels distant, almost like it belonged to a different life. And now, without warning, their paths are about to cross again. Not as student and teacher. Not as they once were. But as two people who have lived years apart... and changed in ways neither of them fully understands. 💌
