I've seen so many comments and stuff saying that Jaeyeon doesn't really like Jimin and will most likely choose Sang Yoon over Jimin. But from what I've seen - I've rewatched the clips MULTIPLE times - Jaeyeon definitely acts different when she's with Jimin and when she's with Sang Yoon. She's more "flirty" and acts more cute, her voice is even a bit higher when she's with Jimin. And based off of the first part of ep 12, her feelings for Jimin is definitely much more than her feelings for Sang Yoon. Plus the chemistry between Jaeyeon and Jimin is definitely one of the best chemistry in the dating show industry, whereas I can't feel any chemistry between Jaeyeon and Sang Yoon.
