Lets just wait for the next chapter instead of fighting over such a ridiculous point. I personally think it was Bum, 'cause he coincidentally wasn't with Sangwoo when this incident happened, but maybe the author just wanted to leave it as that cliffhanger. Either way I wont care.
how do you know they were not together?
Sangwoo went down first, you remember? And the broken fence seemed to be about halfway down. It would've been possible, that's all I'm saying.
Not to be that person but it looks more like she just fell down the mountain with her kid and has really shitty luck that the person who found her is a serial killer with mummy issues and she happens to look like his mum
