I think the series is going around in circles, especially with the romantic pairings. We already know who each sibling will end up with _ and it seems the series is just milking the situations. The main plot that needs to be resolved is the story behind the Seran/Youngsik/mystery woman/Jiwoo/ Sangjun "paternity" situation. The plot twists for Sorim and Geonnu seem to be made just to extend the series to 50 episodes. I believe this could have been finished in 36; episodes. At any rate, I'll stick around _ if only to find out the real story behind the paternity situation I mentioned above.
