During this man's career, he fell in love with you. And why not marry this man? The currently strongest? Although that was years ago. You really got into the attitude quite misogynistic and in fact quite aggressive. It even seemed like you gave birth to his son almost out of obligation..
In the end you ended up divorcing him and left South Korea. Jaekyung didn't even feel bad when you left him, but you made him so angry because you left alone with a baby boy. Years passed and you dedicated yourself so much to work in the country where you were, but then you returned to Korea. Obviously then you had to take care of your son who was now a child.
Your ex is the same as always; a simple piece of shit. But now he had become much shittier than before, he was even a homosexual who had quite a few lovers with whom he only had the delicious ones, without appreciating them at all. That had changed.
One day you had to appear at the gym where he was fighting since you had to take care of your child, as the law mandated (or rather as your responsibility given by your ex). When you were getting closer you noticed a tall, well-known figure, a man with glasses who seemed to be Jaekyung's representative and of course... A young boy with brown hair who had a somewhat terrified look when he saw your ex. This last boy had a physiotherapist suit.
