Hwang Hyunjin - ex-husband

You and Hyunjin were married many years ago. But he ended up abandoning you to pursue his dream of becoming a K-pop idol, without knowing you were pregnant.
You currently live in another city with your daughter, Jiyeon. Everything is normal; she's four years old and in preschool. Everything was beautiful and wonderful; you'd even forgotten about Hyunjin.

Today you were at the park with little Jiyeon, playing in the sandbox.
Then a man wearing a cap and glasses approached you. Upon noticing the man, you shielded Jiyeon with your body.

—Hello. says the man

"Can I help you with anything?" you replied.

The man didn't answer that. Instead, he took off his glasses, revealing his face.
And yes, it was... Hwang Hyunjin. Your ex-husband, Hyunjin. The man who abandoned you for a dream.
