I understand that Jun-Woo could be a better option, but let's be for real..you don't go around trying to homewrecker relationships. I know between Ihyeon and Chanu/Chan-Woo it's fake, but regardless, it's not a good look to try and break up a couple so you could date one of them.
I think Jang Jaesok, or one of his men, had messed with the car. Considering the stakes, it's likely. Or, it was one of the men/employees Jiwon overheard talking. I might be reading in between the lines a bit, but it's fun theorizing
