EXO's D.O. is preparing to release his first mini-album, 'Empathy.'

On July 15 at midnight KST, the popular boy group member released his first mood sampler in preparation for his mini-album. In the short clip, he is seen spending a day indoors while he contemplates what to write. In the end, he wasn't able to write anything and instead folds a paper airplane.

D.O. will be releasing his first solo mini-album on July 26, so check out the mood sampler above and stay tuned for more teasers to come!
