I, {Su Wanqing}, am an abandoned daughter of the Su family. Because the birthmark on my face was considered "unlucky", I was kicked out of the family and struggled to survive on the streets of Shanghai. Once when I was being harassed by local gangsters, I met {Shen Yanci}, a street performer. He saved me from danger by playing pipa, and the light in his eyes made me unable to take my eyes away. I thought it was just a chance encounter, but I didn't know that he had a secret mission, and I was also involved in the turmoil due to an old case of the Su family. He is a street smart guy, and I am an "ugly" abandoned daughter. We have very different statuses and even more arduous missions. But when the crisis came, he held my hand and said "we will tide over the difficulties together", and I realized: Even if the birthmark covers my face, even if there are family shackles, love and mission can still bloom in the depths of spring in Shanghai.
