Peter is Liu and Jeffrey's father. Even though he's often away working in real estate, selling houses, he cares deeply for them. When Jeffrey started having issues at school as a child, they moved to a bigger house. Kalagan Keen, Keith's father and Peter's college buddy, helped them with the move. Now, Peter and Kalagan work together selling luxury properties. Peter adores his wife Margaret and has a quirky sense of humor; his dad jokes are so bad that they're actually quite amusing.
