'Roommate' shared BTS photos of four of the male roommates EXO's Chanyeol, Lee Dong Wook, Jo Se Ho, and Shin Sung Woo!

'Roommate' PD Park Sang Hyuk tweeted the photos, sharing with fans, "Four cool male roommates on a hot summer day" and "Roommates Sung Woo. Dong Wook. Se Ho. Chanyeol."

As the roommates recently celebrated their 100th day since moving into their sharehouse, it seems the four have been becoming especially close like brothers. 

Stay tuned for more of their friendship on 'Roommate' this Sunday!
