Any clues are helpful, whether that would be the actor/actresses name, character name etc. Thanks in advance for taking the time to read this! 

have a nice day!

definetely not a korean drama

if its a drama it's either a chinese with 10-15 min duration drama or shorts they make with 2-3 mins each episode.

Lastly and what i think is most likely to be is that a random chinese couple is uploading such videos online and someone ripping it off.

Sorry couldnt help more :(
