"Coffee and Vanilla" was just too vanilla.

The romance was too sudden and that's why the intensity of it was thrown out of the window. There was an implied love triangle that was easily swept under the carpet only to be mentioned towards the ending. The mature parts were okay, but it looked a bit robotic and forced, lacking any emotion and romance overall. So, the drama was just like this : boy falls in love with popular but childish and naive girl, they get together, many try to set them apart, boy comes to the rescue every single time, happy ending. There was no character development, no love story build up and no surprises. Plus, the leading lady was, as you can guess, the vanilla of the story, and rightly so. She had no personality, claimed to be immature, but she never actually changed, even though there were some scenes that had potential. Her love interest was a more complicated that was never explored.

So, four out of ten.
