EXO-SC's second set of teaser photos put the spotlight on Sehun

A brightly-lit and an almost sterile environment mark the second set of teaser photos for EXO-SC's upcoming July comeback.

EXO-SC is an EXO sub-unit consisting of members Sehun and Chanyeol and will release their first full album called '1 Billion Views' on July 13.

The newly-released photos feature a pink-haired Sehun in a white room with cathode-ray tube television sets. Some photos feature him with numbers projected on his face.

This set of photos feature a slightly different aesthetic compared to the first set which features Chanyeol in a colorful room, with retro-inspired decorations.

Their label SM Entertainment also shared that the duo participated in writing the lyrics for all songs in the album, while three songs are self-composed.

A report from Herald Pop, the pop culture site of South Korean News outlet The Korean Herald, reports that "Telephone." "Fly Away" and "On Me" are the three songs which Sehun and Chanyeol wrote, while hip hop artist Gaeko produced the album.

Geeko also produced EXO-SC's debut mini album 'What A Life' which was released last year.

Sehun and Chanyeol went live on Instagram last night with Gaeko to talk about their album. A song, which fans think is "Telephone" can be heard in the background.

"Aren't we just spoiling the whole song at this point?" Chanyeol asks.

"Exactly, so turn it off. Hyung, how long are you going to play to play it?" Sehun chides him.

They also played another song which fans think is "Fly Away" as Chanyeol is heard saying "Everybody say 'fly away!'" in the video.

The '1 Billion Views' will feature nine tracks, three of which will have music videos.

The album's title track is also called "1 Billion Views" and features the singer MOON.
