When a fan asked him about his personality off-camera, the actor said that he is completely opposite of his current role as Ji Sung Joon. He said rather nervously, "In the beginning of 'She Was Pretty,' I received a lot of criticism for Ji Sung Joon's obnoxious personality. Actually, I think I'm still receiving criticism. However, I'm not like that in real life. Do you see my hands shaking right now? I am extremely introverted."

In addition to questions about his personality, fans also asked if the actor had actually fallen asleep during filming to which Park Seo Joon replied, "I actually did fall asleep (during filming). I fell asleep while filming one cut. I was surprised at myself."

Meanwhile, Park Seo Joon is taking on the role of Ji Sung Joon in currently running drama, 'She Was Pretty.'
