Actor�Kim Woo Bin brought smiles with his post on me2day.

The actor recently uploaded the picture above and along with it wrote, "Go Nam Soon, should I accept your apology[or apple]?", as to mirror the tension between the characters depicted in their drama.

It seems the two actors, who are known to have developed a bond while working on this project, were goofing around on the filming set as Kim Woo Bin is wearing the school uniform he wears for 'School 2013' and is debating whether to accept Go Nam Soon's (played by�Lee Jong Suk) apple.

This is a play on words because the Korean word for apology is�sa-gwa which is a homonym for apple.�Fans commented, "You guys should win the best couple award," "Make up and become friends," and�"This what you call playing hard to get!"

On another note, Kim Woo Bin plays the role of Park Hoong Soo in 'School 2013'.
