Doom at your service is an excellent supernatural drama. For a kdrama lover it surely has its highs. The acting of Seo-Inguk and Park Boyoung is upto the mark. Apart from the main characters the second leads also have a definite story line which gets you hooked up. It's nothing like any typical kdrama. You feel happiness at one moment and at the same time you feel pain. All the emotions are portraited on point.
