17:51 Thank you Yuhwan!!!! I thought it was just me. I don't want to be a conspiracy theorist, but I swear to God every time Yoochun wants to come back, some crazy person writes a trash article about him. It looks like some people don't want him to come back to the industry. I have some theories, but I think it's better not to talk about it here.😂 I really hope someday Yoochun speaks out and tells us the truth.
