What's Wrong with Secretary Kim S01E04 - I Come Back to Forgive You

Young-Joon's brother Sung-Yun, who happens to be Morpheus, the renowned writer of romantic novels, returns home. The fight between him and Young-Joon ensues before their mother breaks the conflict. Later that evening Young-Joon visits Kim Mi-So and she tends to his cut lip. While she didn't have time to tidy up her place, she quickly put some of her undergarment under the stuffed bull. As Young-Joon notices the bull upside down and tries to flip it, Mi-So screams and runs to stop him only to end up on top of him on the bed. After the shock subsides she tries to stand but Young-Joon hugs her and pulls her closer.
