Sister in law Without Underwear

Min-jeong and Hyeon-soo have just gotten married and are enjoying their honeymoon when Hyeon-soo’s younger brother, Kang-tae, comes to visit. Min-jeong finds herself feeling an inexplicable attraction to Kang-tae, who is unusually kind to her. However, because he is her brother-in-law, she tries to completely cut off those budding feelings. Meanwhile, Min-jeong’s friend Na-hee, who has been spending time with Kang-tae, realizes that he has feelings for his sister-in-law. Min-jeong also confides in Na-hee, admitting that her heart keeps being stirred by her brother-in-law.
