On the August 20 installment of KBS radio program, 'Lee So Ra's Music Plaza,' Taemin talked about hypothetically having an older sister.

He was asked, "If you had an older sister, is there a member in SHINee you would like to introduce to her?"  Taemin replied, "No.  If I had an older sister, I don't think I would introduce her to the SHINee members."

He went on like a cutely protective and possessive younger brother, "I think I would get jealous if my older sister met somebody.  She's my older sister, so I don't think I would like it if she showed interest in someone else."
