There's so much to say about the plot (and it isn't positive) so instead of typing paragraphs and paragraphs, I'll say three things. One, Cha Eung San should've asked both Choi Young Do and Kim Tan to FUCK OFF and should've focused on her studies, Kim Tan and Choi Young Do should've left her the FUCK ALONE (seriously man wtf was up with them, following her around, basically harassing her till the point of submission), and, although I don't like bullies in TV shows or otherwise, Choi Young Do was fucking hot and even if you wanted a good story, Cha Eung San should've ended up with HIM and NOT Kim Tan. That's all.
Oh, and if you're going to watch the series anyway, be ready to pop a blood vessel or two, it's really frustrating to watch. <3
