On the February 19 airing of tvN's 'Talk Mon', Sojin said she thinks playing around barefoot is the most romantic skinship.
Fellow guest Park Ji Woo startled her as he said, "Under the blankets?" Sojin replied, "Just playing around with your feet. Like when you go playing in the waters and stuff. I think that's lovely."
MC Kang Ho Dong playfully commented, "So do you also take off your socks when you go into restaurants?" To this, Sojin brought laughter as she regretfully said, "I should've just said back hug (as the most romantic skinship)."
