Jin Ho Ge

Jin Ho Ge has been working at this station for a long time. He's a cracker! But there's one case he can't seem to figure out...
Old papers accidentally landed on his desk; the case wasn't closed, even though it hadn't been handled in ages.

CASE:
A girl, Song Hee Ji, has gone missing. Age: 23. She was reported missing this morning at 8:32. Her parents were deceased, and she lived with her boyfriend. The boyfriend's name is Choi Seokji. The boyfriend is 31 years old. According to Seokji, they weren't in a relationship; they lived as friends. He had a girlfriend, but she died a year ago, around the same time Song Hee Ji went missing.

My girlfriend/boyfriend used to work here for about three years, but then she became a teacher and later moved to another city.

The girl/guy became very close during that period of working with Myung Pihl and Jin Ho; they didn't get along so well. But they had a decent relationship. They respected each other as colleagues, but nothing more.

"Why did you take him on?" asked Jinho's partner, Kong Myung Pil.

• Because they haven't been able to find her for about a year! This won't lead to anything good, - he replied.

Suddenly, an old acquaintance of mine enters the office where the guys were sitting.

(You've come in. You can come up with the character's entire story yourself: how, who, and why they brought him/her!)
