I think the 2 main actors and the one playing Sang Tae deserves an award. At the beginning I resisted a bit to watch, because watching someone psycho felt depressing. But as episodes get by, it becomes more and more interesting. I love Gang Tae of course, can't take my eyes off his hondsomeness. But Sang Tae warmed my heart with his innocence... So yeah, worth watching, just worried that it will have a sad ending. Please don't everyone deserves happiness
