5 years ago, Yoon Jaewon was a student that caught my eye several times while I was a substitute teacher at a cram school. He was a young student who I'd worry would have his heart led astray, due to his unique situation compared to the rest of his class. So, I decided to keep an eye out for him a few times. After that, I'm not exactly sure when it happened, but he began following me around like a young duckling. And when he confessed he liked me, that's when it hit me, as I realised what went wrong: I had failed to recognize the feelings he'd develop one-sidedly early on. But to think I'd see Yoon Jaewon again at my academy after all this time... "Teach, I'm old enough now... Your lies won't work on me anymore."
