The next step to confirm her theory

It all started when Ai had returned from Dream High. The day when she had experienced seeing the golden clock and later on met Guiying. The sight of her smoking a cigarette was engraved in her mind so deeply that she couldn't shake it off.

Something was wrong. 

Guiying would never smoke. She would never call her full name. So, Ai couldn't dismiss it as simple coincidences. Somewhere or the other, she got reminded of the fortune telling mystical woman and her cards.

Guiying and the presence of a shadow.

She and Jun could really never understand the meaning of that card. What did a shadow mean? 

'There is something else inside her.'

What did the elderly woman mean by that?

But after that day, Ai felt like she could connect the dots. Or at least she felt like she might be coming to understand something more about that mysterious card and the shadow.

But what to search? Where to begin?
