Seo In Guk revealed he used to get beat up because of his eyes.

On the February 16th episode of the YouTube series 'Ssulpy', Seo In Guk featured as a guest, and he and SG Wannabe member Lee Suk Hoon went out to interview people. Seo In Guk made eye contact with one person, but he was disappointed when the person turned away immediately. Hearing this, Lee Suk Hoon said, "I know. Your eyes are scary."

Seo In Guk responded, "I was hit a lot when I was young. They told me, 'Don't look at me like that,'" to which Lee Suk Hoon commented, "They're eyes that call for a misunderstanding."
