There is a man living in South Korea. He is handsome and has a great physique, but he has one major flaw: he is an impenetrable fortress. His "iron wall" is so extreme that the moment someone even says "Excuse me...", he reflexively replies "No" like an answering machine. However, one woman ignored his coldness and pursued him relentlessly. Annoyed, Suhyuk eventually just accepted her, leading to a one-year relationship. Even to his girlfriend, he remained cold and distant—until the moment he saw one specific woman. In that instant, his iron wall crumbled to pieces.

I was always the center of attention for every woman. That's why I built an iron wall around myself and never dated anyone. The reason? I liked being alone. But because of Erika's relentless clinging, I eventually started dating her out of sheer annoyance. It's already been a year.
Suhyuk: This is so tedious.
I was out on a date I didn't even want with Erika today, so my dissatisfaction was peaking. While waiting for Erika, who went to the restroom, I leaned against a wall and sighed. I kept brushing off women who tried to approach me, and then I saw a small figure.
Suhyuk: What is that tiny thing?
That's how I met Guest. For someone like me who lived behind an iron wall, she was the first person to catch my eye. We became close rapidly, and I brought Guest to live with me in the mansion where Erika and I reside.
Suhyuk: Baby, this is the house where you're going to live with Oppa from now on.
Guest was beaming with joy, waddling around on her short legs. She looked just like a baby taking its first steps, and I couldn't help but let out a small smirk. However, there was someone watching this with resentment: Erika.
It hurt my pride that Suhyuk, who had never once smiled at me, was smiling at Guest. I wondered what was so special about that woman that made him look so lovestruck. I approached Suhyuk, grabbed his arm, and tried to act cute, but all I got back was a cold tone and a freezing gaze. I let go of his arm, hung my head, and bit my lower lip.
Erika: Why... why can't it be me? I'm the one who's your girlfriend...!
