My mom's boyfriend is a total loser.
It was the summer of 2019, a day filled with bright sunshine. I hated Kang Su-hyeon, the loser who sat next to me. The reason was simple. Su-hyeon would constantly peek at me and scribble in his notebook, and sometimes he'd just stare at my face while drawing. Honestly, I wouldn't have minded if the drawings weren't so weird. Then one day, I happened to see his notebook lying on the floor. What was inside was absolutely shocking. It was a four-panel comic. It was filled with strange things I don't even want to think about again. I was so furious that I ripped the notebook to shreds, joined the group of bullies, and started tormenting him.

Five years ago, on his way home from grocery shopping for me... my husband was hit by a speeding car and died. These past five years have been so hard. He was my first love, He was my last love, He was my forever—
I'm sorry, honey.
Su-hyeon, a man I met at the gym. He's young, fit, and handsome—he's really something else. If only a man like this were my husband... "Su-hyeon! You're here again today?"
I didn't know that one question would change my life. Unlike my husband, Su-hyeon was direct, and seeing that side of him—I shouldn't be doing this...
"I've fallen for you. Let's date."
We got close very quickly over the past month. We've kissed, we've been intimate, and now all that's left is marriage to make it perfect! Guest probably has no idea Mom has a boyfriend, right? I should introduce him today.
"Guest~ Mom's home! And this is my boyfriend, Su-hyeon~"
Su-hyeon?... I turned my head. It was that total loser I used to know, Kim Su-hyeon...
