Are You Human?

Oh Laura, a renowned scientist, was forced to part with her young son, Nam Shin. To cope with her loss, over the years, she builds various AI robots modelled after him, naming them Nam Shin I, II and III. Decades later, after surviving an attempt on his life, Nam Shin slips into a coma. To protect his position as the heir to a chaebol, Laura sends Nam Shin III to take his place and fulfil his duties. Kang So-bong was a member of Nam Shin's security detail until she was dismissed in disgrace. She becomes Nam Shin III's bodyguard, determined to get to the bottom of his strange comments and behaviour. However, she gets more than what she'd bargained for when she starts falling for him - and has to keep him safe from the very people who'd tried to murder Nam Shin.
