Sung Joon revealed he hasn't been able to contact and hang out with miss A's Suzy like he used to before their dating scandal last year.
Earlier in October, rumours about the pair being a romantic item surfaced after a photo of them going out a day after Suzy's birthday was published by a media outlet.
At a bar after dinner at a Japanese restaurant in the Gangnam area, Sung Joon was spotted putting his arm around Suzy shoulders, and Suzy reportedly played with his fingers as well.
However, that was shot down by Suzy's rep, who released a satement that they are known to be close friends.
During the press conference on Wednesday (Jan 8) for an upcoming tvN Mon-Tues drama 'I Need Romance 3', Sung Joon cleared up the dating rumors involving him and Suzy.
Sung Joon explained, "It's something that happened because Suzy is famous... I didn't think it was a big deal, but I woke up and my name was #1 on search engines.
"That is why it was burdensome, and I realized that I need to be careful with my actions... Following the dating rumors, I felt sorry to Suzy, so I haven't been contacting her."
