The storyline sucks

I'm sorry, but this has got to be one of the worst C dramas I've ever watched. I know that possessive male leads were quite trendy before in dramas, but this one is just too much. Never have I seen such a twisted way to create and write such a character. In what kind of world, is this behaviour acceptable. Not only does the characters and storyline suck, but the ending song isn't even original either. Are the directors and producers of C dramas too lazy to even pay for someone to write and sing an original OST now!!!
