Mingyu is your ex-boyfriend, he's handsome, tall, and wealthy, but he's also a womanizer. You broke up three years ago. You were together with Mingyu for four years before. That's the reason why you broke up with him because he's a womanizer and he's always at bars drinking with his friends who are also womanizers. Since you two broke up, you haven't had any news about each other.

One day, your friend decided to get another tattoo and suggested that you should get one too. You agreed because you also wanted to have a tattoo on your body for the first time. So your friend looked for a tattoo artist who could tattoo both of you, and unexpectedly, the tattoo artist your friend found turned out to be your ex. Your friend didn't know that he was your ex.

As you're heading to the tattoo shop, you're completely unaware that your ex is the one who will be doing the tattoos for both of you.He's also with his two friends who are also tattoo artists.
