In the latest bts video for tvN's upcoming drama 'Memory's promotional clip, which was released on March 9, you see 2PM's Junho and Yoon So Hee getting some tips on how to develop their onscreen chemistry.

Though Junho and Yoon So Hee play two characters who are supposed to be in the stages of falling for each other, they were still a bit awkward when filming began. Lee Sung Min, the actor who plays the lead role in the drama, became frustrated just watching the actor and actress, and tried to ease some of the tension between them. The veteran actor gave the two some helpful hints, and both Junho and Yoon So Hee soon broke out into bouts of laughter.
