Kai was the charming and flirty member of EXO. He was very handsome and y, but would at any moment turn to a cute aegyo prince. He immediately fit perfectly into any given concept and looked good in all of the clothes they were supposed to wear. He did everything at 100% from dance moves and photoshoots to interviews and fan meetings and was always cheerful. He looked perfect doing everything. Most importantly he stole every fan's, girls and boys, hearts with his smile and charm. He was the 'perfect boyfriend/dad' material and everyone adored him. 

That was D.O's first impression of Kai too, but soon he'll learn that there is much more in that boy.
