hiraeth,
(n.) . a homesickness for a home to which you cannot return. The nostalgia, the yearning, the grief for the lost places of your past.
When kwon chin-hae woke up after the incident , he didn't remember anything of his past. Not knowing his family, he followed his saviour as a worker in the games. He's learnt not to ask questions.
Three years later, a particularly stubborn girl entered the game and for the first time, chin-hae remembered scattered fragments of a forgotten life, making him question everything he knew. He doesn't know who she is, but he does know that he's going to get her out of this deadly game, no matter what.
