When did Xiao Jian and Haruko meet in Princess Zhu Huan?

This is the last episode of the second "The Wedding of Swallow and Wei Zi".

Xiao Jian and Haruko fell in love at first sight.

I've heard Swallow and Wei Zi talk about Xiao Jian before, and I'm also interested in this strange man who has friends everywhere, can play flute and dance sword, and is very familiar with Jianghu.
