looks was not the problem in this show i could careless.... but explain to me in reality who dumps someone with no explanation in the real world and especially someone who fell in love even if he didn't come to you as a gentleman love is love you can't just stop loving someone yet alone without no explanation... they just rushed the ending to give us some what of an expiation about the APP but they forgot to tell us why she put the shield on and brushed it off by showing us that she did not use the app when she was in her new relationship with hye young and the spear was her trying so hard to show that she loves him but still that was her new relationship and her old one with Sun Oh has no answer even after season 2
