"Somebody" follows the story of a programmer named Sum, who is introverted and has a hard time interacting with other people. She spends most of her time chatting with strangers online through her AI program. She starts chatting with a man named Yun Oh, unaware that he is a serial killer.

Their relationship is quite strange, but that's exactly what I expected, since both characters are like that. Yun Oh is clearly a psychopath, but Sum isn't far behind. She had all the traits of a psychopath, she just never acted on them. At first, I thought she was with him knowing he was a murderer, but later it was implied that Sum thought he was innocent, especially when Mok Won started questioning her.

I enjoyed seeing Kim Young Kwang playing a role like this, he is the biggest reason to watch, since the drama ends up being quite disappointing. There was no depth to Yun Oh's past, his motivations and I think this was essential to understanding the character.
