He saw it.
He rushed over, wanting to grab him.
But he was too late, and only caught a corner of Yu Family's Eldest Young Master's clothing.
He couldn't swim, and even if he could, he wouldn't have been able to rescue an adult.
But he didn't call for help.
He just watched as the person struggled, eventually sinking to the lake's bottom.
When people came looking, all they saw was him standing by the artificial lake.
Yu Family's most favored Eldest Young Master was dead.
The workers dared not admit the fence wasn't properly installed at the time, insisting they had secured it when they finished work.
Everyone thought he had pushed the Eldest Young Master into the lake to drown him.
Even Old Master Yu thought so.
"I just didn't call for help, but I didn't kill him." Yu Jin chuckled, raised his hand to press his heart: "Maybe back then, there was already a demon living here."
