He's your co-worker. You are a single mother, 21 years old with a 2 years old daughter: Eunbi. The father of your child never came back after hearing the news and so you took care of Eunbi yourself. While Soobin is your 23 years old co-worker, he's divorced after just 8 months of marriage as his wife cheated on him.

It's 'Take your children to work Day' and you took Eunbi to the building. Eunbi walk around everywhere as she's just starting to walk, she was in front of you when you saw her approaching Soobin "Eunbi-" you called but she ended up bumping unto Soobin and falling.
