Mouse is an upcoming thriller Korean drama airing next month on tvN. The series stars Lee Seung Gi as the naïve young officer Jung Ba Reum and Lee Hee Joon as the lawless detective Go Moo Chi. The two will be working together to track down a predator who's the "top 1 percent" of psychopaths.

Mouse also stars Park Ju Hyun as Oh Bong Yi, a tough high school student. She excels in all kinds of sports, such as jiu-jitsu, martial arts, and boxing. She and Lee Seung Gi's Jung Ba Reum were neighbors and their relationship will be one of the interesting parts of the series.

The recently-released stills of the upcoming drama showed how Jung Ba Reum and Oh Bong Yi's dynamic will play out. The two can be seen talking about something while they were both standing near the entrance to their neighborhood.

Jung Ba Reum stopped Oh Bong Yi, who was just passing by him. He, then, showed her a flyer stuck to the wall. But then, it seems like she does not care what he's going to say as she turned around and walked away from him.

Lee Seung Gi's character looks concerned towards Oh Bong Yi but gives him a cold attitude instead. It's interesting to see why Park Ju Hyun's character acts differently toward Jung Ba Reum, given that he's known for having positive energy in their neighborhood.

The latest stills of Mouse hint that there could be a deeper connection between the two. Their relationship might be more than just between a police officer and a high school student. Despite differences in their characters, Lee Seung Gi and Park Ju Hyun warmed up the set off-cam.

The two shows concern for the staff while filming the scene amidst the cold weather. The production team praised them, noting that both of them are actors that "complete scene after scene with their thorough preparation and earnest attitudes."

The crew added that viewers should look forward to the "bickering chemistry" between Jung Ba Reum and Oh Bong Yi. The former is considered as the number one choice to be a suitable son-in-law in the neighborhood, while the latter is a problematic high school student.

Meanwhile, the latest teaser of Mouse featured Jung Ba Reum and Go Moo Chi. The two were talking about the psychopaths, with Lee Hee Joon's character saying nobody knows what these people are thinking on the inside. Then, the clip featured people exhibiting different emotions and behaviors. 

Mouse will premiere on Wednesday, March 3 at 10:30 PM KST, on tvN.
