INFINITE's Sunggyu talked about his first love and first kiss on the February 6 edition of KBS 2TV's 'Happy Together 3.'

He revealed that he experienced his first love and first kiss in middle school.  He then went into a story of how these two experiences actually overlapped, "In middle school, I was at the gym with my girlfriend when she told me she was transferring.  That was like a sign to me that I should kiss her," which made everyone ask in confusion, "Why?"

Sunggyu revealed what he thought his girlfriend was thinking at the time: "I'm going now. I can't see you anymore."  This made him think he had to kiss her, so he did to express how much he liked her.

Her response was, "I like."  The other cast members started to have fun with this, repeating the phrase and saying it was funny she said this even though Sunggyu didn't ask her anything after.  

He said, "I stopped her from transferring through this kiss," which shocked everyone into believing this must have been some legendary kiss.  This, in turn, made the cast members tease Sunggyu even more.  Yoo Jae Suk joked saying that a kiss to this extent could have stopped past wars.  

They then brought up that Sunggyu was known to get upset easily.  He admitted this was true in the past, but it's not the case anymore.
