It comes full circle. (spoiler alert)

This was basically a masterpiece. I actually clapped when Jin Ah told Joon Hee why she couldn't go with him. I just think it's a great work the creators have achieved, to create a narrative that justifies its own destruction. You might be sad that they break up but if you're honest with yourself, this was inevitable. The whole journey was for Jin Ah to finally reach a point where she wouldn't put a man above herself. Joon Hee helped her achieve that growth and confidence but it ultimately destroyed them. That was just so perfectly captured.
