As Long as You Love Me Episode 13

Let the power play begin

Where the first twelve episodes focussed on building the relationships between characters and personal problems, episode 13 made it interesting by finally adding plot twists that weren't spoiled already in the summary of the show. Where we start with some sweet moments and many shed tears, the angst gets added within minutes and we're back to our icy war. It brings us back to 0 with our main couple but external problems add twists, which makes it more interesting to watch than previous episodes.
