Stars of new drama Flower Boy Next Door Park Shin Hye and Yoon Si Yoon showcase how close they've gotten in this cozy photo shoot for InStyle. The actors say they've become very comfortable with each other, after the time they've spent working together on the new series, and their comfort shows!

Both actors speak very highly of each other. Park Shin Hye remarks that her co-star always seems studied and well prepared, not to mention polite and kind. Yoon Si Yoon says that one of the biggest reasons he was excited to be a part of this drama is because he heard Park Shin Hye was on board.

With all the sweet, mutual admiration these two have for each other, it doesn't seem like this new drama can go wrong! Who's already got plans to watch the January 7 premiere?
