Apr 03, 2021

tvN’s “Mouse” released a new behind-the-scenes look at the drama!

“Mouse” is about an innocent and upright police officer named Jung Ba Reum (Lee Seung Gi) and a hardened detective named Go Moo Chi (Lee Hee Joon) who believes in nothing but revenge against the serial killer who murdered his parents. The two team up to track down an evil psychopathic predator.

The new making-of video begins with Lee Seung Gi and Lee Hee Joon rehearing for their upcoming scene. They are in high spirits as they discuss the best way for Lee Seung Gi to choke Lee Hee Joon. Lee Hee Joon jokes, “It hurts. Let’s hurry up. Let’s do it in one go.” Fortunately, the scene is done in one take, and when asked if he’s okay, Lee Hee Joon claims, “It hurts!”

Next, Lee Hee Joon teams up with Park Ju Hyun for the scene where he visits her house and tries to make her come live with him. The two rehearse first, but she ends up laughing at his unexpected lines. She looks inside the bag that he was supposed to fill up with her belongings and comments, “You didn’t even pack anything,” and he quips, “I’m going to!”

During break, Park Ju Hyun points out Lee Hee Joon’s character became too cute after Lee Seung Gi’s character turned dark. She imitates the way he widens his eyes, and he sheepishly admits, “I’m supposed to [act that way because I have to] believe his theories, but I do think I turned into a fool.”

Lee Seung Gi and Lee Hee Joon also film with Song Jae Hee, who stars as a psychotic lawyer in the drama. During rehearsal, Lee Hee Joon rambles on and on, and his long lines cause Lee Seung Gi to laugh and Song Jae Hee to try to cover up his own smile. In response, Lee Hee Joon jokes, “Just hear me out a little more.”

Lee Seung Gi and Lee Hee Joon continue to practice their lines. Lee Hee Joon points and tells him to go get a warrant, and Lee Seung Gi scrambles off in the wrong direction. Lee Seung Gi runs back while laughing in embarrassment, and Lee Hee Joon can’t stop grinning as well. Lee Seung Gi tries the scene again, and this time, he bites his lower lip to stifle his laughter. Lee Hee Joon cracks up and comments, “How can you laugh while making your exit?”
