Lee Jong Suk may be one of the most popular actors of his age, but Girls' Generation's Yuri reveals a weird and quirky habit that he does in order to get close to someone.

On March 12, idol group Girls' Generation appeared as guests in the variety talks show "Radio Star", and member Yuri talked about being friends with actor Lee Jong Suk. She revealed, "The first time I met Lee Jong Suk, he shocked me so much when he suddenly bit me."

She continued, "I thought, 'What planet did he come from?'. I felt like he was an alien for having such a weird quirk, but I realized that it was his unique way of befriending people."

Yuri and Lee Jong Suk worked together in the sports film "No Breathing" back in 2013. During a press interview for the movie, Yuri brought up the topic, and said, "Maybe it was because he was embarrassed, but Lee Jong Suk bit my arm after making a mistake."

"It's my way of being close to her," Lee Jong Suk explained. "I only bite those who I'm affectionate with."

Meanwhile, he will be appearing in the upcoming drama "Doctor Stranger" on SBS after the conclusion of "God's Gift - 14 Days".
