My reunion with her took place in the worst possible way.

That night, she was dragged to the Bureau of Civil Affairs. Wait, after getting the marriage certificate, the husband ran away? And his identity can’t be found? OMG, did she marry a human or a ghost?

Disheveled, she entered the entertainment industry and almost got sexually assaulted by a director due to the unspoken rule. Young Master Moh suddenly reappeared, and that director was tortured before getting cancelled.

During a shoot, she almost died since her enemy wanted to destroy her. Then, hundreds of mysterious soldiers arrived and smashed everything. The producer was exposed of corruption and his life got destroyed.

Young Master Moh had to cover his forehead; he needed to teach her how to behave like a senior officer’s woman.
