Desperate hunger what happened abruptly from the start

Answer

닥쳐오다. 오다 means "come". “닥쳐오다” is the combination of 닥치다 & 오다. 
닥치다 itself has the meaning of coming but with the emphasis on coming very near site and the approching quickly.
닥쳐오다 means "come quickly to nearer site or time point".  닥쳐오다 and 닥치다 have the similar meaning.
