Forget about the actual ending, it sucked. What I want to talk about is the love triangle between Yu-zhi-->Kau-jung<--So-ning. Half-way through the series, Kau-jung had to come to grips with the fact that there are two wonderful girls who are in love with him. He is in love with them also, but which one does he love the most? Which one would he choose to marry?
Near the end, he wants to find out for sure. He sets up these two dates. First, he takes So-ning out for a walk, and then they watch fireworks together. These are fireworks that Kau-jung arranged especially for this date.
Next, he takes Yu-zhi on a walk, and they sit down in the middle of a field and watch the stars.
Which girl do you think he loves the most? Think symbolically.
