Hong Kong Film and TV Universe: The Roy-Catching Plan

Every character here is one played by Zhang Yaoyang

1v1, both leads are each other's first and only love

Days in the Underworld*Yang Gang

The Mission*Ah Mai

Prison on Fire*Yan Guoxiong

School on Fire*Da Fei

These are the ones I've thought of so far. I'll add more if I think of any.

Just a short, sweet story. It's not very well written, so please don't blame the cook. Thanks...
