You and Seokjin were once a married couple, but your relationship ended after 2 years of marriage. The reason you guys divorced was because of lack of communication, Seokjin often left you because he was taking care of his business in Los Angeles. So your relationship slowly cracked because you rarely met, Seokjin only came home occasionally on the end of the month. That's what makes you and Seokjin sometimes tense with suspicion.

5 years later, you're checking into the hospital holding your son, Seojun, who has a fever.

suddenly your bag fell and a man immediately helped pick up your bag. "Here is your bag, come here let me help you carry your child" without you realizing it is your ex-husband who is helping you.

"let me carry him, you can finish the registration" he said smiling briefly then took Seojun from your arms.
