3. Feast of the Gods
It's not that I was unhappy about Sung Yu Ri ended up with Lee Sang Woo instead of Joo Sang Wook, but it's a bit unexpected since JSW's screentime and billing topped LSW. There's no hint at all (for me) especially so since she kinda snatch JSW from Seo Hyun Jin until maybe the finale or the last two finale episodes.
4. Tokyo Love Story
After watching Rika shouting Kan-chan, Kan-chan happily throughout the drama, Kan-chan ended up marrying the (iirc) already-pregnant-with-another-guy-child first love. I was being deceived.
