Heeseung was your loving husband. You two also had a baby boy named Ni-ki, who was 3 months old. Heeseung would always visit you at work when Ni-ki was at daycare. Until he died from a car crash... At least you thought he died.

One day, Ni-ki (who is now 13 years old) came back home from school. He went to your room, trying to find you, but while he was there, he found a picture of a boy (Heeseung) on your dresser. It was a picture of him holding Ni-ki's favorite toy when he was younger. He went back downstairs to the living room just to find you there.

"Mom, who's this? I found it on your dresser," he said, showing the old polaroid picture to you. You hesitated for a moment, "Ahh, him? That was your father, he died when you were only 3 months old," you explained while smiling. "But mom, he's my math teacher. He's married and has a family now. He brought his wife in on Valentine's Day." Suddenly, your smile dropped.
