The newlywed couple of "My Daughter Seo Young," Park Hae Jin and Choi Yoon Young had their very first fight as a couple.

During the 45th episode of KBS 2TV weekend drama "My Daughter Seo Young" which aired on February 16th, Choi Ho Jung (Choi Yoon Young) found her husband Lee Sang Woo (Park Hae Jin) was peeking at her blog and became frustrated with him.

Choi Ho Jung was pleased with the romantic plans Lee Sang Woo did for her and showed off to her friend. The friend said, "the Lee Sang Woo I know isn't that caring. He must have read your blog."

Choi Ho Jung didn't believe her friend but tested out if Lee Sang Woo really secretly read her blog. Lee Sang Woo asked her to cut his nails and said that she could use his arm as her pillow. After he said that, she knew immediately that he has seen her blog. Choi Ho Jung said, "you would? You don't have to. Did you see my blog?"

Lee Sang Woo said, "is it so wrong for me to do what you want?" Choi Ho Jung said, "you can do that when I become an old grandma, but I hope that you would really do that when you love me. Not doing it forcefully."

Lee Sang Woo suggested the next day for them to see a performance so that she would feel better. She was in a better mood, but then heard a phone conversation he was having and misunderstood him once more. She then began walking away from him.
