What is the whole point? Let's supposed we're 100% sure about where he lives and we're right. And then what? Call the police on him? If so, don't we already have enough evidence to do that? Or someone is thinking about killing him?
What I concluded:
> Bonbi was e-dating this retard
> this retard is more retarded than he should be, to the point it's dangerous for Bonbi to be with him
> we're the good guys, so we catch him
> we punish him
That's it? Goog enough for me, actually. By reading some prints it seems like Bonbi feels betrayed, so him being punished might even make her happy, since she doesn't hold any feelinds for him anymore (if she ever had any and it wasn't just some usual horny teeanger shit).
