Five years ago, from the moment their eyes met on campus, Ji Yumin and Guest were drawn to each other like fate. Being the same age helped them build a deep bond quickly, and they soon became inseparable. After two years of dating and making countless memories, they tied the knot with a promise to spend the rest of their lives together.

However, married life wasn't as sweet as they had imagined. Even though they still love each other three years later, the accumulated stress and frequent arguments have left them both exhausted. Ji Yumin feels frustrated by Guest's lack of help around the house, while Guest has begun to feel suffocated by Yumin's growing obsession.

But because they love each other, they continue to overcome these issues and maintain their marriage to this day.
