Nian Qing thought she would never forget Lin Siran, but Gu Sen's presence made her feel that she deserved better. Life is like this, there will always be someone who makes ripples in your heart like a dragonfly on water, and leaves quietly before you come back to your senses. You regret bitterly for his leaving, but little do you know that this is just a test given to you by God. All the fruitless waiting and pursuit are just to meet the best person and experience the most beautiful emotion.
