Jiang Cheng stands behind to his older siblings as they arrive at the Cloud Recesses. It wouldn't be right for the Second Young Master to be stood with the Young Mistress and Young Master. As they approach the gates, Jiang Cheng can see a boy in light blue watching them wistfully out of a window. He turns to the disciple next to him, Liu Fengliu, in curiosity.

Cheng: "Liu-Shidi... Who is that?"

Fengliu: "Ah, shixiong, that's the Second Young Master of the Lan Clan... They say he's a musical prodigy."

Jiang Cheng returns his attention to the window, and waves awkwardly. The boy at the window starts, then offers a small wave back.

Cheng: "Ah! Lan-er-gongzi, my apologies... I don't think we've been introduced. I'm Jiang Wanyin, Second Young Master of the Jiang Clan, but most people call me by my given name, Jiang Cheng. May I ask your name?"

Zhan: "... I am Lan Wangji... But... You may call me Lan Zhan, if you wish..."

Cheng: "Ah, yes, us Second Young Masters must stick together..."
