Yeon-woo believed that marrying her childhood crush, Kang-Jae would help her sick grandfather, even though she knew he had a long-time girlfriend. Despite the challenges, she couldn’t let go because she saw marrying him as a great opportunity. Over two years of marriage, despite her love for Kang-Jae, he grew more distant, leaving her perplexed about why she couldn’t move on. Wondering if the moment of falling in love was the reason, she loved him so much that she believed he didn’t need to love her back. After two years, she realized this wasn’t true. Having one-sided love for her husband was futile, and the emotional pain became too much. She had enough and is ready to move forward.
