Yeah, the more I thought about it, the more I figured there was no way it'd be real. In the promo, where Jung In is just chilling on the ground while Tae Yeon takes care of the baddies, that's not her style. She wouldn't just sit there and let that happen. But still, couldn't there have been just one daydream kiss. Aye.
I also must say that I'm glad some of the victims were killed lol.
