In still cuts from the drama set, you can see the actor in all modes of styles, clad in snappy suits, sweaters, and even the staple Korean ahjusshi comfort gear: the track suit. Yes, he even rocks the track suit like no other. 

The actor's agency relayed, "Park Si Hoo is doing his best for 'Neighborhood Hero' role Baek Shi Yoon after his three-year hiatus. I think that Park Si Hoo immersing himself completely in the filming was captured nicely in the drama. He will give it his all for just the role of Baek Shi Yoon. Please watch him until the very end."
