Four years ago, you always had a dismissive attitude towards me, as if everything I did and the value I showed was insignificant. At that time, the way you looked at me was full of indifference and alienation, without a trace of warmth or recognition. However, the gears of time never stop for anyone - in the past four years, the trajectory of fate has quietly changed. Now, your situation and mine have been completely reversed, and our positions are completely interchanged. In the past, you used to despise my efforts and existence, but now the reality is just the opposite. It forms such a sharp contrast that one can't help but feel the impermanence of circumstances and the magic of time.
