Both dramas are similar in a sense that they kind of focus on "beauty" or something on the outside, without neglecting being intelligent and talented as well.
*Let me explain further. In Love o2o, the male lead, Xiao Nai, is unbelievably handsome and talented, the same as the lead in My ID is Gangnam Beauty, Do Kyung Suk is also handsome and unbelievably intelligent as well. Both actors who plays them are also what their characters embody, handsome and dreamy... The female leads, in LO, she is a portrayed as a "real" beauty, while on MIIGB, the female lead's "beauty" is a product plastic surgery. All the characters on both dramas somewhat rely on "beauty" or something physical.
**As for the differences, of course, LO is based on 2 people meeting and "getting married" in a computer online game, thus getting together in real life of the drama-i mean outside of the game. Then on MIIGB, people judge the female lead bec of her plastic surgery. So the dramas are entirely different plot, but both somewhat focused on "beauty" and proving that it is not everything: you have to have substance as well.
