Bum's smile makes me so sad because he looks so carefree and happy for the first time. But the fact of someone ruining things *cough sangwoo cough* is horrible...like I want bum to be happy but it seems he can't be happy without sangwoo.....but sooner or later I hope he realize what kind of person he is by knowledging the fact he is not good enough for him and he could do so much better liek DAMN LOOK AT HIS SMILE dont fucking tell me he can't get anyone..
I think her secret is that she killed the father....just saying djskskej
Again,... didn't Sangwoo once say to Bum that, before that one old man they killed together, he hadn't killed a man since his dad (that before the old man, he had only killed women ever since)? That means he was the one who did it, or at least he participated. Taking into account that his mom also wanted a secret for herself that she didn't have to share with either Sangwoo or with his dad (in the same way as they both were keeping stuff from her) she can't be talking about killing Sangwoo's dad, since Sangwoo would have to have known about it too, if he did indeed help her with it (and if, as we have established, for that earlier conversation with Bum to make sense, he had to have at least participated).
