I skipped to the end because i wanted to find out the mystery but ???? Can someone explain...

so basically the grey haired girl, bojin, slept with her boss or smby in her work place and the main character guy, hyung soo, took photos of it before he knew who she was and it ruined bojins career. So the whole investigation was them trying to find out who took the photos but throughout the story they don't really focus on it a lot so it kinda gets confusing. I hope that makes sense lol

Thanks for that!

Ofc ofc (^з^)-☆
