Why did 2PM's Taecyeon give miss A's Min a back hug?

On this week's 'Entertainment Relay', 2PM's Taecyeon caused some buzz because of his interaction with miss A's Min. The JYPE Nation members came together for an interview about their 'JYP Nation Concert  - Team Play'. Just as Taecyeon was wrapping up the interview with "We're..", he accidentally hit Min on the back of her head with his hand. Immediately, Min reacted by clutching her head, and the other members began laughing out loud over the mistake. An embarrassed Taecyeon then gave Min a back hug in apology.
