An Huai has been coveting Shao You's face and body (fog) since she was a child. An Huai has been in love with Shao You since she was a child. After persisting for ten years to no avail, she decided to give up and wanted to get out, but found that she couldn't climb out of the pit.
Shao You later realized that his feelings for An Huai were more than just a habit, so he held down An Huai who wanted to crawl out. Couldn't he? Then change to a bigger hole :)
Intention: Persistence is victory. If you ignore me today and ignore me tomorrow, you can't reach it!
