The two met on the set of drama 'Oh My Venus'. Sung Hoon commented, "It was during our first script reading. Henry sat next to me and touched my thigh."
Henry, who is fond of skinship, responded, "I thought it was your hand." However, the actor shook his head in denial.
Sung Hoon also mentioned, "I don't ever do video calls with Henry. He keeps kissing the screen," making the viewers burst with laughter.
They really do seem close!
