Watdog's Things

I forgot whether it was a manga or manhwa but it was like...MC was asking for directions to somewhere and he asked this dude who was kinda(?) mad about it but then still told him. MC was like okayyyy.. then he went back to that place another time and he saw the dude he asked working there...i think it was a coffee place...not sure and there were scenes where it seems the MC was playing an MMORPG in his phone or something.
