This genre is not my usual cup of drama tea, but I got curious about all the hype. For me, the story is nothing new, bigamy and such, and maybe that's why kdramalandia got caught up in it. It is reality, added with a sprinkle of bonkers. The good directing, acting, and music all presented a familiar story in a suspenseful way, and sometimes that's all it takes. As with other dramas, it lost steam on the 2nd half of the drama, esp. the ending which is lackluster for me (that's it?), and some storylines were left hanging.
