Last year, the 33-year-old actor portrayed a charismatic novelist and radio DJ, Jang Jae Yeol, who suffers from obsessive-compulsive disorder (OCD) due to his abusive childhood in the highly rated TV series It's Okay, That's Love. In-Sung demonstrated the character’s complex personality smoothly and convincingly, to considerable acclaim. On February 28, In-Sung visited Bangkok to meet Thai fans at the So In Love with Zo In-Sung Fan Meeting at JJ Mall.
Unlike at other fan meetings, the actor focused on a very long interview about his lifestyle and work. He joked around a lot, teasing fans who admitted that they hadn’t watched It's Okay, That's Love, telling them to leave the hall and come back later after watching it. Only four lucky fans got to take close-up pictures with him. One of them impressed In-Sung when she said she had waited 10 years to meet him. The actor ended the meeting by singing a fun song, “Thinking,” by the group Hot Potato. Though he isn’t a professional singer, his adorable voice made his Thai fans very happy.
