miss A's Suzy (19) was spotted on an outing with her 'Book of the House of Gu' co-star Sung Joon (23), raising rumors about the two being a couple. As if timing couldn't be any better, media outlet Sports Seoul released the report of their alleged date that took place back in September a day after Suzy's birthday (October 10). Suzy was spotted with a friend on the 24th. The two of them took a taxi to Seorae Village where they stopped by a villa and switched cars to a silver Mercedes Benz, which Suzy drove herself. The two picked up model-turned-actor Sung Joon along the way. The trio visited a Japanese restaurant in Cheongdamdong, Gangnam where the three enjoyed dinner, laughing and smiling. They then headed to a bar where they sat at a discreet location so that Suzy wouldn't be recognized. Although it could have been interpreted as just a meeting between friends at this point with another female friend present, after exiting the building Sung Joon was spotted putting his arm around Suzy's shoulder. According to Sports Seoul, Suzy didn't seem to mind and played with his fingers showing her affection as well. With fans wondering whether the unrequited love on 'Book of the House of Gu' between the two co-stars had actually blossomed into real-life romance, a rep from JYP Entertainment responded with the quickness: "Suzy and Sung Joon are known to be close friends. They also meet up often with their 'Book of the House of Gu' co-stars Lee Seung Gi and Lee Yoo Bi. They have a mutual friend who they ate and spend time with. Suzy and Sung Joon are just close colleagues." Another agency rep also confirmed, "Suzy and Sung Joon are just friends. They are definitely not dating."
