Read this on soompi, please please please let this be true!
Apparently Miju stops Min Woo from offing himself (why? I don't mean why she stops him, I mean why was he going to?), he ends up having a short jail term and when he's out she meets him with Wooju and they can all be a happy frelled-up family together. Now, this doesn't really solve any writing problems, either in general (tons of plotholes, nonexistent revenge plan, characters who got dull) or on MW/Miju front (are they even going to have time to address the whole 'her family hates his guts and vice versa' thing or 'ooops, I lied and Wooju is your son' thing or the whole 'Miju kept pushing him away for no good reason and then Min Woo went evil' thing) but at this point, I've given up on Giant being as good as it was in the first half and will just settle for a happy ending for my OTP, however half-baked.
Meanwhile, have a few awesome angsty MW/Miju scenes:

However much of a mess Giant has become by now, I will always have warm feelings towards it because it gave me Min Woo/Miju.
