The best on-screen bro-mance I've ever seen. How can you NOT fall in love with Byun Yohan and his grinning smarmy-ness?! (He was similarly smarmy in "Misaeng".)
Bonus Kyle from Thunder Bay!
I think my life would be infinitely better to be able to witness Yoo Yeon Seok (the grumpy samurai) as Hedwig in person. Alas, not in this lifetime.
