The young cast members of JTBC's trending drama 'SKY Castle' appeared as guests on the January 31 broadcast of KBS2's 'Happy Together'!

SF9's Chani, who plays the role of Woo Joo in 'SKY Castle', told his side of the story regarding the time he spoiled the drama's storyline while fellow group member Youngbin was watching at their dorm. 

When asked to clarify, Chani revealed, "It wasn't a spoiler. The main broadcast had already aired, and the member hyung was watching a rerun episode... He was watching the episode, and I just said without thinking, 'Oh yeah, Hyena falls off in this scene,' which made him cry... I thought he was rewatching the episode, so I pointed out that Hyena noona's fall scene was coming up, and he was so sad." 

However, Youngbin's side of the story from earlier in January was a little different from Chani's account. You can catch a clip of Youngbin talking about how Chani surprised him with a major spoiler while he was watching the drama, below. 

When mentioning Chani's spoiler during a 'V Live' in January, Youngbin complained, "Why did you tell me... I wanted to watch it... why did you tell me... and Chani just said, 'Oh, did that part not come out yet?' Of course it didn't... It was something I was supposed to wait until this coming Friday to find out. Chani just said, 'Oh, I didn't know. I thought that part was already revealed'... It makes sense for Chani to get confused. Chani is Woo Joo. Woo Joo must film scenes from episodes 15-20 here and there in random order, so he may get confused."

What do you think about Chani's account of the spoiler incident, and Youngbin's account?
