"I will be the next sect leader and I promise Master I'll protect the Manor"
"So...if you stay here, I'll protect you too" That was his first promise to Wen Kexing.
"Well then, when we marry. This will be my home too!" Wen Kexing smiles widely, both his eyes turn into a slit. He showed his left pinky towards Zhou Zishu.
"So I'll promise to protect it too" Zhou Zi Shu raised his right pinky and interlocked his finger with Wen Kexing.
"Ok..." Zhou Zi Shu never realized their pinky promises would last a lifetime.

Zhou Zishu and Wen Kexing were childhood sweethearts. Their marriage was arranged since they were babies. However, at their first meeting, they promised to protect each other and Four Season Manor. Despite all odds, they grew fond of each other. They get married and Wen Kexing gave birth to A-Xiang. But Zhou Zishu had to leave again and again. It was a childish pinky promise. Does it mean the promises are destined to be broken?
