Jo Se Ho put on another lip-syncing performance in the car, and this time Nana sang along to SoyuXJungGiGo's "Some". In the preview, Jo Se Ho told Nana, "This is the first time that I visited a rest stop with my girlfriend,"�to which Nana fired back, "What? I am not your girlfriend." Everywhere they went, Jo Se Ho kept on introducing Nana as his girlfriend, and Nana kept drawing the line on their relationship, "I'm just a girl. Don't add 'friend' [to the word]. [I'm just a] girl."

Will this blossom into another love line? Stay tuned to find out on 'Roommate' this Sunday at 4:15 PM KST!
