Welcome back to another installment of For Your Viewing Pleasure, where we take time out of the week to curate a set of photos from the K-pop landscape.

There is this saying, “good things come in pairs,” and these images definitely mark that statement to be true. Siblings Han Sun Hwa and Han Seung Woo exhibit their playful relationship for their 1st Look shoot, while Irene and Seulgi of Red Velvet are double trouble in the concepts for their sub-unit promotions of Monster. Oh My Girl‘s Hyojung and Seunghee smile up at the camera as if they were actually caught in a carefree moment while picnicking. Opposites attract are on the mind with vocalist Hyunjae and dancer Juyeon of The Boyz. Dressed in all white and all black, respectively, the two demonstrate their comfortable dynamic even without their nine other members around.
