First of all, this is solely my opinion and I do not judge anyone who liked it.

Personally, for me, Cheese in the trap gives off the same vibes as Nevertheless. (But not as steamy as Nevertheless, if you know what I mean ;) )

Same moody, angry-ish, scary-ish ML, but IMHO unlike Park Jae Eon (Song Kang's character in Nevertheless), Yoo Jung really is a manipulative and very scary character, who only got interested in Hong Seol just because he thought she was like him. He is mostly emotionless, cold and brutal.
Even though Hong Seol is a pretty good character, who developed throughout the series, I still think that her choice of staying with Yoo Jung was just plain stupid.

Baek In Ho (SKJ) - I admit, I suffer from SML syndrome, but choosing Yoo Jung instead of Baek In Ho was worse than in True Beauty (I mean Hwang In Youp <3 lord have mercy).

Most of the characters in this drama are just trash
Hong Jin Tak (Hong Seol's dad) - incompetent, arrogant, childish, abusive
Kim Yeong Hee (Hong Seol's mom) - just meh... putting all her worries on her daughter, without giving it a second thought. She didn't even new her daughter's friend's number to call them. All they cared about was the younger brother.
Hong Joon (Song Seol's brother) - well.... not too bad.

But the worst of them all - Baek In Ha. Just her name makes me cringe, I mean she takes the cake, of all the K-dramas that I have watched, THIS is the most horrific character of them all and no disrespect to Lee Sung Kyung, her acting skills are improving from one dorama to another.

THE ONLY light in this horrible group of people is Kwon Eun Taek (Nam Joo Hyuk) - Lovable, goofy, caring, sweet, charming, friendly, loyal... all the good qualities that a person could have <3


Overall, I gave the score of 3, even though the plot is kind of interesting throughout the whole drama, they just killed it and made it just trash... again, IMHO <3
